Hugh Laurie is nearly as snarky as his character Dr. Gregory House. In an interview on The Tonight Show (November 16, 2005), he told Jay Leno he uses the cane on the wrong side only because physical therapists told him he was doing it wrong. He wanted to be ornery.
He also told Jay that he'd now flown his first plane, a Jaguar fighter bomber. After throwing up twice, the pilot told him to take the controls and fly the plane himself although he'd never flown before and didn't have a license.
