Jay Leno has millions in the bank, but he doesn't always spend like a millionaire.
Besides his auto collection, which consists of vehicles like the legendary McLaren F1, the comedian is pretty frugal. He hates spending on clothes and still hasn't touched a dime of his "Tonight Show" money.
"I'm not a big splurge guy," Leno tells CNBC Make It, partly because he had Depression-era parents: "They just frightened me to death, saying, 'You gotta save every penny!'"
Perhaps that's why the self-made millionaire still uses coupons, even for fast food.
