I LOVE Robert Downey Jr. I think he's a brilliant actor, especially when he's doing something funny. Like the scene below of pure comedy gold from 'Tropic Thunder', where Robert played an Australian method actor playing a black man. As his character Kirk Lazarus puts it - "I know who I am. I'm the dude playin' the dude, disguised as another dude!"

Here's the Never Go Full Retard scene... incredibly un-PC, but friggin' funny!!
