The vampire defends the joker!

Robert Pattinson recently took a bold stand for fellow late actor Heath Ledger, when a rude jokester crossed the line during a stand-up act.

According to a witness at a No on H8 show (which aims to fight back against the passing of Prop 8) at the Improv in Hollywood, Robert was none too pleased when a comic gave an "impression of Heath Ledger" by falling on the ground and convulsing.

Alongside booing the comic's antic, the source told Us Weekly, "Robert and his friend went nuts yelling at him. [Pattinson screamed] You suck!"

Hmm... Looks to us like Robert sure knows the difference between a good and bad joke...(we have a feeling the Joker would be proud!)
