When I first started out, I was considered a crackpot. The doctors used to say, "Don't go to that Jack LaLanne, you'll get hemorrhoids, you won't get an erection, you women will look like men, you athletes will get muscle-bound -- this is what I had to go through.

Who puts the food in your mouth? Who goes to the bathroom for ya? You do. You came on this earth alone and you are going to leave alone. Think about it. If anything happens to Jack La Lanne good or bad, I made it happen. If anything happens to you good or bad, you made it happen - right?

How many cars out there look like Corvettes? You want something nobody else has. You don't want an old look-alike thing, and that's why Corvettes have the reputation of being one of the fastest cars.

For the money, Corvette is tops.
