The 32-year-old actor, who stars alongside Natalie Portman in forthcoming film No Strings Attached, said that he believes that humour is a great basis for a relationship, and that it even has a place in the bedroom.
He told E! Online that it came in handy when trying to film sex scenes for the new movie.
'Inherently, I find that having sex and intimacy, when it's great, it's funny,' he said.
'The real challenge was, you've got 50 people looking at you, you're with someone you don't really know, and you're trying to make sure they're comfortable, you're trying to be comfortable, and now, you've gotta be funny.'
