Bam Margera is learning the hard way ... the folks at YouTube do not take kindly to self-induced golden showers posted on their site.

In case you don't follow Bam's career ... the MTV star is now getting into the rap game ... and one of his videos started to get some heat on YouTube.

Problem is ... the video ain't exactly family friendly ... containing some incredibly graphic images (naked people) and some unusually graphic hydration techniques (Bam takes a drink from his own yellow fountain).

Also, the lyrics were a bit too racy for YouTube ... since the hook is basically a description of how Bam wants to bend a particular body part in an unusual way so that he can have sex ... with himself.

A rep for YouTube tells TMZ ... "The video was taken down because of the content. It was flagged by users and a policy team believed it contained too much sexuality per our terms of use."

Prolly for the better.

Al Roker's crazy pants-pooping hijinks have impressed the master of all things dung ... and now Johnny Knoxville says he's inviting the weatherman to SHART in the next "Jackass" project.

Knoxville -- who has featured several real-life crapping scenes in his "Jackass" flicks (including the infamous poo-cano) -- was in L.A. last night when we told him about Al's dirty little secret.

"That makes my day," Knoxville said ... adding, "If Al Roker ever wants to shart in 'Jackass,'  he's more than invited."

Roker hasn't been shy about his little slip -- going on "Dateline" and "Today" to talk about the time he tried to fart at the White House ... and crapped himself instead.

Bam Margera says his herpes sore is GONE following his crazy run-in with a naked, masturbating female intruder ... and tells us he only wants to see the woman get help.  

As TMZ first reported, Margera claims he woke up in the middle of the night to find a woman trying to kiss him, and when he went to call police ... she laid on the floor and started masturbating.

Bam claimed a cold sore sprouted on his mouth following the incident -- and believes it's the result of direct contact with the woman (ew!!!) or from the stress of the whole thing. But last night in Hollywood, Bam recounted the ordeal for us and gave us the good news ... his cold sore has cleared up.

Bam says he's not interested in pressing charges and just wants to see the woman get help.

Starting with a shot of penicillin, perhaps?

Bam Margera is convinced the naked chick who broke into his house and masturbated on his floor ... might have left a little gift behind as well -- HERPES.

Bam and his friend Tony Hawk posted a video on YouTube ... where Bam tells Tony everything that went down the night his alleged stalker was arrested two weeks ago -- including the part where she pleasured herself in front of him.

But then the "Jackass" star drops a bombshell -- he says he woke up the day after she busted in with a giant sore on his bottom lip.

In other words, he thinks she might have given him the herp when she kissed him -- or, Bam admits it could be the stress of the whole mess.

The naked girl who allegedly broke into Bam Margera's house and masturbated on his bedroom floor didn't just appear out of nowhere -- she had secretly been LIVING in Bam's tree house for weeks ... the "Jackass" star tells TMZ.

As we first reported, cops arrested the 24-year-old woman Friday in the area surrounding Bam's Pennsylvania mansion ... and according Bam, the girl told police she had been living on his property for weeks leading up to her wild bedroom invasion.

Bam tells us ... the girl had been camping out in the giant tree fort on his property -- the same fort featured as Fast Eddie's Treetop Casino in an episode of "Viva La Bam."

After she was arrested on charges of burglary, criminal trespass, and stalking, Bam says cops found evidence the girl had been living in the tree house -- including clothes and garbage.

But she didn't just hole herself up in the treetops -- Bam says the girl had knocked on his parents' door a couple of weeks ago with luggage, claiming she had moved from Florida to marry her son. Bam says his mother sent the woman away ... after trying to set her up with a homeless shelter.

As for the woman, we're told she's still in custody -- being held on $50k bail.

This might be the CRAZIEST THING that's ever happened to Bam Margera ... and that's saying a lot -- the "Jackass" star claims a naked chick broke into his house last night while he was sleeping ... and started masturbating on his bedroom floor.

According to law enforcement sources, Bam told police the 24-year-old woman woke him up in his Pennsylvania home by kissing him -- completely in the buff -- and Bam freaked ... throwing the girl off him and dialing 911. 

And here's where it gets really insane -- according to law enforcement sources, while Bam was on the phone with cops, he claims the girl dropped to the floor and started to masturbate.

After Bam hung up, we're told he kicked the girl out of his house -- still completely naked.

West Chester police tell TMZ, they arrested her nakedness in the rural area surrounding Bam's mansion.

According to the criminal complaint, she faces charges of burglary, criminal trespass, and stalking.

"Jackass" star Bam Margera wound up being dragged through a North Carolina airport in handcuffs this weekend ... for allegedly being a drunken pain in the ass ... and TMZ has the pic.

Bam spent several hours in a holding cell at the Charlotte Douglas International Airport on Sunday after airline employees refused to let him on his flight ... because he reeked of booze and was cussing like a sailor ... this according to the incident report.

Officials say ... Bam got loud and combative... and cussed even more ... so law enforcement was called in, handcuffed Margera and immediately removed him from the area (above).

TMZ spoke with Bam ... who admits he was loud and obnoxious ... but insists he was NOT drunk at the time. Bam says the alcoholic odor was merely "left over" from a bender the night before. 

After he was released from the holding cell, Bam says the airline booked him on a later flight ... which he boarded without incident.

We reached out to the Charlotte airport police ... but so far, no word back.

Bam Margera's guts busted through his abdominal lining when he plummeted over a 100 ft cliff in a kayak ... and now TMZ has obtained footage of the stunt that sent Bam to the E.R.

We broke the story ... the "Jackass" star needed emergency surgery to fix a nasty hernia he sustained during the kayak stunt at an Oregon waterfall last week with pro kayaker Steve Fisher.

In the footage, Fisher warns Margera to "tense everything" before they go off the cliff -- but when the duo smash into the water, the force of the impact was so intense, Bam was ejected from the vessel ... and he suffered damage to his abdominal wall.

Moments after the stunt, Bam was seen smiling and laughing ... but he soon realized something was wrong and went to a hospital ... where doctors performed emergency surgery to treat the hernia.

When we caught up with Bam after the incident, the daredevil told us he might need more surgery in the fall.

In his latest desperate bid for a Darwin Award, Bam Margera kayaked off a 100-foot cliff in Oregon two days ago ... and he landed his ass in very familiar territory ... the hospital.

Bam tweeted the picture yesterday, claiming he had to undergo an emergency hernia operation following the tandem kayak stunt with pro kayaker Steve Fisher.

It's unclear if Fisher was also injured during the fall -- but one thing's for certain ... they're both really, really stupid.

Get well soon.

Bam Margera spent Fat Monday in the custody of the New Orleans Police Department ... after the "Jackass" star got arrested for getting a little too crazy during a Mardi Gras party.

TMZ obtained photos of Bam being escorted into a police station Monday after he was detained by 3 officers in the French Quarter.

We reached out to Bam and asked if he was officially arrested ... and he replied, "Yeah, I was swimming in a pool with my clothes on at Mardi Gras."

He added, "Not really a good story ... but that's what happened."

Sources tell us Bam was soaking wet when he was taken into custody ... and was handcuffed at the scene. 

Bam has since been released -- so far, it's unclear if he was charged with a crime.

Bam Margera got himself some fresh ink this week – a tattoo of his late pal Ryan Dunn on his right shoulder.

Margera, fresh off a few broken ribs from falling down the stairs, got the tat done by the same guy who does Lil Wayne's stuff.
