The Camera Does Add Ten Pounds

As the "Friends" watch an old home movie from a Thanksgiving when Monica was heavier:

Joey: Some girl ate Monica!
Monica: Shut up! The camera adds ten pounds!
Chandler: Oh. So how many cameras are actually on you?

As far as the NBC Studio tour guide I met is concerned, the camera does indeed add ten pounds. Why? Because the studios like to shoot with wide-angled camera lenses: it can make a small set look much bigger on TV. But as a result it can make the actors on that set look a little bigger as well!
