"So I said, 'OK, Mom, I'm going to change it.' And for my mom's sake, I made it 'The Tonight Show with Jay Leno,' so I didn't look like a showboat."
The self-made millionaire and current host of CNBC's "Jay Leno's Garage" has never let his massive success get to his head or change his core beliefs.
