Tom was dressed as Loki. Loki is the Norse God of Mischief and Mayhem. That's how his character is. Nobody calls Johnny Depp a sick for doing the same thing while he is in character. Geez.
Not only is it hard to wash off, it's also very difficult to get out of clothing. Even more so when it comes to a costume that can't be traditionally laundered. That's not just a one time prank, that's either going to be an issue that's going to come up *every time* RDJ puts the suit on, or a shitty, shitty day for an intern.
