Mozart just rolled over in his grave ... but don't worry, it was only because this video made him really excited.

Thanks to the awesomeness of the Internet some chick named Sara X took to YouTube to show off an amazing talent ... bouncing her boobs to the tune of a song with no hands.

This time, she chose the Mozart classic "Eine Kleine Nachtmusik" -- and it's AWESOME!

Have you seriously not started watching this video yet?!

She does, however, know one -- Oprah -- who can help her navigate her new-found fame.

Jimmy Failla -- the taxi driver who rode around with a snake in his cab and then posted riders' reactions to YouTube -- has lost his cabbie license ... but tells TMZ he's gained a slew of new job offers.

Jimmy tells TMZ the Taxi and Limousine Commission yanked his license for two years, but Jimmy is more than ok with it. He says he's gotten two TV development offers, his stand-up career is taking off and he's even auditioned for a slot on "The Tonight Show."

Failla says he's even been approached by producers to pull the prank in Los Angeles, though he says he'd need a fake taxi.

A NYC cabbie who pranked passengers with a live snake -- and posted their reactions to YouTube -- doesn't give two craps if the Taxi and Limousine Commission yanks his license ... he tells TMZ, he's on to much bigger things now.

Check out Jimmy Failla's video above -- it's pretty funny -- but New York City's TLC isn't laughing ... calling the prank "monumentally poor judgement on the driver's part." A rep says the commission is now actively reviewing Jimmy's TLC license. It's up for renewal next week.

But Jimmy tells us, if TLC wants to take his license away ... they can have it.

He says he shot the YouTube video to promote his new book ... and he's also making a living as a stand-up comedian -- so he doesn't need to drive cabs anymore. He never really liked doing it anyway.

During last night's game between the Memphis Grizzlies and the Chicago Bulls, ESPN's Jon Barry either dropped a very causal F-bomb or ... well, we really don't have another option.

As Grizzlies center Marc Gasol drained a midrange jumper, Barry remarked, "four f**king jumpers he's knocked down."

It's possible Barry said something else (one site postulated he was trying to say "flat-footed" jumpers), but it's clear he got a little tongue-tied.

BALLER runs in family ... 'cause Randy Moss' daughter just dropped 63 points in a college basketball game in one of the most DOMINANT performances of all time.

Sydney Moss WENT OFF for Thomas More College in a 106-88 victory over Waynesburg in a DIII tournament in Kentucky on Friday night ... setting the DIII single-game scoring record.

Moss -- a 5'11" sophomore -- is sorta following her dad's college career path. She started at the University of Florida and then transferred to the smaller school.

Of course, Randy started at Florida State before transferring to Marshall ... where he emerged as one of the best wide receivers in the country.

David Lee Roth and Mike Love may not be surrounded by California girls anymore ... but that didn't stop them from getting together to sing about how much they still love 'em.

DLR and Love hit the stage with John Stamos at an ELAA Awards benefit in Beverly Hills -- and despite their age (Roth is 59; Love is 72) ... both performers were pretty spry on stage.

David Lee Roth's version of the song was released over 20 years ago.

Kanye West went on another endless rant Saturday night ... but this one had a racial twist.

Kanye was playing the Prudential Center in Newark, New Jersey when he called out TMZ and other media for criticizing him over the last year.

Kanye said we all make him look like "a maniac and an animal" ... not because of anything he did ... but because of our discomfort over interracial relationships.

Unless we're missing something ... he thinks we all have a problem with the fact that he's engaged to Kim Kardashian.

Bruce Jenner's oldest son Burt Jenner went nuclear on the paparazzi Thursday ... berating them for screwing with his famous family. Problem is ... most of the photogs didn't know Burt from Adam.

Burt owns a dog sitting business. The paparazzi swarmed Burt's parking lot after getting wind of a big celeb who was inside a building across the street.

The non-famous Jenner was indignant, ordering the photogs -- not ours -- to skedaddle. Their response -- Who the hell are you?

That's all Burt needed to hear. He had his employees get in their car and block the photogs from leaving.

Everyone screamed, had a bad time ... and the video is awesome!

"Staind" singer Aaron Lewis is slamming the country hit, "Redneck Crazy" by Tyler Farr ... saying it promotes violence toward women -- so he had the whole thing re-written.

Lewis says he HATES Farr's song -- about an angry guy who stalks and threatens his ex-GF.

Sample lyric: "I'm gonna aim my headlights into your bedroom windows/Throw empty beer cans at both of your shadows."

The song -- which appears on Farr's debut album -- immediately shot to the top of the country charts ... and features some "Duck Dynasty" stars in the music video.

Lewis broke out his alternate version during a performance at a little bar in Medina, Ohio.

The 33-couple wedding during Macklemore and Ryan Lewis' performance at the Grammys was the feel good moment of the night ... except for one man -- who did everything he could to stop the love of his life from tying the knot.

Michael Politz tells TMZ ... he learned Sunday his ex-girlfriend Tammy (pictured below last night) would be saying "I Do" to her new dude during the "Same Love" performance ... and went into a panic trying to shut it down.

Michael says he called everyone under the sun who might be attending the awards ... so they could tell Tammy how he felt -- including Vince Neil -- but none could make it happen.

"I'm heartbroken" Michael says. Adding, "I don't know if I'll ever trust again."

Newlywed Tammy Grabel tells TMZ ... "Michael is a broken hearted ex-boyfriend. Seth and I are very happy to be married ... I had no idea Michael was trying to stop our wedding."

Guessing he assumed it would end like this.

Move over Vince Vaughn ... DMX just opened up shop on a group of groomsmen heading to their buddy's wedding -- and the footage is AWESOME!

The groom's wedding party ran into X Saturday afternoon in their New York hotel lobby ... and after the rapper posed for some pictures they boarded their party bus -- says one of the groomsmen.

Inspired by the meeting, the group turned on some of DMX's music and egged him to hop aboard ... and that's when the magic happened.

Jay Z did NOT pull a fast one on his audience in Greensboro, N.C., Sunday night ... when he brought a 12-year-old boy up on stage who stole the show -- it was all spontaneous.

We spoke with Angela, who took her 12-year-old son Justin to the concert in Charlotte Saturday. She says Justin's dream was to "get noticed" by Hova and he was crushed when he was overlooked as he sat in the 8th row.

Angela says on the ride home they decided to give it one more try, and she bought tickets to the Greensboro concert the next day. She says she was lucky and scored front row seats.

Angela tells us nothing was set up. Justin jumped up with his sign and this time Jigga noticed.

Jay Z just gave a 12-year-old kid the chance of a lifetime ... and the kid delivered.

Jay discovered the pint-sized rapper sitting in the crowd at his "Magna Carter World Tour" concert Sunday in Greensboro, NC -- he was holding a sign that read, "Can I rap for you?"

Jigga pulled the lil' guy up on stage ... and the kid laid down a crazy interpretation of Jay Z's rap. Jay even cut him off ... just before he spewed some curse words.

Britney Spears got the lead out for tonight's big Las Vegas debut.

Brit's friends and family were there for her final dress rehearsal for the "Piece of Me" show ... and she did not disappoint.

Britney is back to her old self onstage ... her dance routines blew everyone away. Her singing ....

Zac Efron has taken a page out of Alec Baldwin's playbook ... when something bad happens, turn it into a joke and people will laugh.

That's exactly what Zac is doing -- without saying a word in a new video that makes fun of how he broke his jaw last month.

As TMZ previously reported ... Zac claims he slipped in a puddle of water at his Hollywood Hills home. His jaw broke and he gashed his face.

As you know .... Zac has been to rehab twice this year for cocaine abuse.
