Ben Stiller...

he looks like he wants to choke/kill a bitch right now. I kinda think the guy can't poke fun at himself too much, or take other people poking fun at him...

Must Ben Stiller's dad have a cameo in every Ben Stiller movie?

(Note: Tropic Thunder may not apply, as I haven't seen it)

Gladys Knight and the New Pips.
