10:30 AM PT -- And just when you thought it couldn't get any better ... we just posted more video.
Reese Witherspoon wasn't kidding when she told GMA she was "saying all kinds of crazy things" ... and TMZ has obtained the entire, unbelievably entertaining dash cam video.
The footage, obtained from law enforcement sources, shows the officer arresting Reese's husband Jim Toth for DUI in the early morning hours of April 19.
Reese -- who since admitted she was hammered at the time -- decided to butt in during the arrest ... and the officer obviously wasn't having it and cartoonishly enforced the law with a vengeance.
In fact, the cop warned Reese several times to sit down and be quiet so he could focus on Jim -- Witherspoon didn't exactly comply.
Instead, Reese got in the officer's face ... and annoyed him to the point that he arrested her for disorderly conduct. Here are some of Reese's finest quotes during the incident:
Reese: "Do you know my name sir?"Officer: "Don't need to know." Reese "You don't NEED to know my name?"Officer: "Not quite yet."Reese: "YOU'RE ABOUT TO FIND OUT WHO I AM!"
Reese: "I have done nothing against the law."Officer: "Yes you did, you didn't obey my orders."Reese: "I HAVE TO OBEY YOUR ORDERS??"
Reese: "I'm now being arrested and handcuffed??"
Reese: "I'm an American citizen ... I'm allowed to stand on American ground."
Reese: "You better not arrest me."
Reese: "I'm being anti-American?"Officer: "Yes, please sit down."Reese: "Wow!"
Reese: "You're harassing me as an American citizen"
And the best line -- "I'm obstructing your justice?"
After Reese's tirade, Jim actually told the cop, "I'm sorry, I had nothing to do with that!"
During the arrest, Reese also told the cop she was pregnant and needed to pee. She later confessed on "GMA" that she panicked and said "crazy things" because her husband was being arrested.
Funny moment during the bust ... the officer instructs Toth to blow hard during a breathalyzer test -- coaching him along the way, "Blow! blow! blow! blow! blow! blow! blow!"
But Toth blew TOO HARD ... and the cop had to do the whole thing all over again.
We broke the story ... Reese pled no contest to Physical Obstruction of Another and Jim pled guilty to DUI.
