Much like Don Draper, Jon Hamm seems to have a sordid past that he can't seem to get away from. Earlier today, a lawsuit from 1991 surfaced that accused Hamm of being involved in a violent fraternity hazing while he was in the Sigma Nu fraternity at the University of Texas.

In the lawsuit, which was obtained by the Associated Press, the actor, along with some of fellow frat brothers were accused of hazing pledge Mark Allen Sanders in 1990. Over two decades ago, three of the accused were sentenced to jail for 30 days. "Jonathan Hamm of St. Louis" had a warrant issued in his name in 1993 but it wasn't until 1995 that the actor made a plea deal and received probation.

Sanders claims that Hamm became "mad, I mean really mad" when he couldn't recite facts about the other fraternity brothers. Sanders maintains that Hamm retaliated by shoving his face in dirt, set his jeans on fire and paddled him.

"He rears back and hits me left-handed, and he hit me right over my right kidney, I mean square over it," Sanders recounted in the lawsuit. "Good solid hit and that, that stood me right up."

2015 doesn't appear to be Hamm's year. Last month news hit that the 44-year-old completed a 30-day stint in rehab stint for a problem with alcohol.
