Harry Potter star Daniel Radcliffe has snubbed the chance to take the comedy act he wowed castmates with on the road - because he's convinced he isn't that funny. The teenager admits the Potter cast and crew are forever encouraging him to become a stand-up comedian after he kept them laughing between takes with his jokes and wisecracks. But Radcliffe insists he'd be too nervous to actually try to be funny for a living. He tells Parade.com, "I'm very flattered. I could never do stand-up because it's that thing of having to get up on stage, and, out of every 10 jokes you tell, nine of them have to get a really good response. "I don't think I could do that. If I didn't get a big laugh every time, I might wither."
