Ben Affleck: "I can move my scalp and [make] people think I have a wig on."

Alicia Keys: "I am the best at cracking my neck. People tell me I'm going to break it, but I haven't found the discipline to stop."

Justin Guarini: "I can actually snap my toes, like other people snap their fingers."

Rosie O'Donnell: "I can balance anything on my finger, including furniture--tables, chairs, anything. Nobody would believe me, but when I was on my show I started doing it and people were like, 'Will you stop?'"

Robin Williams: "Ventriloquism and naked juggling."

Dustin Hoffman: "I can blow a bubble on the tip of my tongue. It's really small, like a pea. You give it a 'pfluft' and it floats off. Kids love it."
