In what episode does Chase get punched? i can't think of the name of the episode, but is it Act your Age?

He gets punched por House in Finding Judas. In Act Your Age he gets jumped and bitten por a kid with a thing for Cameron.

You're talking about Finding Judas I think. In that episode House is a real jerk's jerk. That's when he punches chase and when he coldly tells Cuddy that its a good thing she fails to become a mom because she sucks at it.
