He was one of the stars of the movie "Dazed and Confused," and according to police, it's also the best way to describe his night in Scottsdale.
That mug shot is pretty embarrassing -- but it wasn't the most embarrassing thing that occurred during a chaotic night in Scottsdale for the actor.
Police say he had signs of "extreme alcohol impairment" -- but it's what investigators say he purposely did in the back of the squad car that has everyone talking.
Dazed and Confused star Jason London looked a little dazed and confused in his mug shot, taken after being arrested at a Scottsdale bar Sunday.
The 40-year-old was cited for assault and disorderly conduct. The actor allegedly sneezed on and punched a patron at Martini Ranch on Stetson Drive.
"Once our officers got there they were confronted with a very intoxicated Mr. London who was belligerent and swearing and didn't want to have any treatment whatsoever," said Scottsdale Police Sgt. Mark Clark.
According to the police report, London repeatedly told officers he was a rich and famous actor. Officers say the antics continued in the squad car.
"At one point he defecated in the back of the car and that was on the way from the bar where he was arrested to the jail."
Around 3 p.m. Tuesday London took to Twitter saying: "I would never say or do the crap they are reporting... Some guy thought I was hitting on his girl and had me jumped. ...I hate Arizona... wait till you see the real pictures. I have a right orbital fracture and sinus fracture. The truth will win."
"Scottsdale's a nice place to come and visit but if you get overly intoxicated then your experience is probably not going to be that good," said Clark.
The backseats of squad cars are plastic and are hosed off after cases such as that.
Assault and disorderly conduct are misdemeanors. Police say he likely won't face jail time, but fines, and possibly will be ordered to do treatment if he needs it.
