Brian Bonsall, who played Andrew, the youngest Keaton on the NBC sitcom Family Ties, was arrested in Boulder, Colorado for assaulting his girlfriend. She told police that he threw an alcoholic drink in her face while she was asleep, choked her, and threw her onto a bed. Bonsall says it was all in self-defense, because she cut him with a steak knife.

"Well it's like we've been together, for a million years..."

This isn't the first time Bonsall has been in trouble with the police. In 2001 he was convicted of drunk driving, and in 2004 he was arrested for the same offense.

If you didn't watch Family Ties, Bonsall played Worf's son on Star Trek: The Next Generation and starred in the movie Blank Check.
