Adrian Peterson Smiles for Mugshot

Minnesota Vikings RB Adrian Peterson got in a bit of trouble over the weekend...and now his absolutely wonderful mugshot is out. AP has quite the grin for a guy who just got arrested in a nightclub.

TMZ says the owner of the club says AP was "wasted" the night he got arrested, which surprised him because Peterson doesn't usually drink much when he's at that club.

Apparently Peterson wanted to get one more drink before last call and was refused. AP then allegedly tried to intimidate the bar tender into pouring one more, that's when an off-duty cop intervened and things got crazy.

According to the club's owner, Peterson apologized once he was subdued by the police and said he doesn't usually drink.
