Ed Helms has been cracking up fans of The Office with his portrayal of the eternally lovelorn Andy Bernard, but as he tells Rachael, there was one actor who always had the rest of the cast in stitches. "Any scene with Steve Carell was a wash," he says. "They couldn't even pan to other actors because everyone was laughing the whole time."

Audiences got to see even more of Ed in his film, Cedar Rapids ... because he had a nude scene! "The producers were like, 'How are we going to get the female audience in?', and everyone agreed, well, let's just show some of Ed's backside," he deadpans, "because it's the sexiest thing in the universe! It's all for the sake of comedy, so why bother with dignity?"
