'Oprah's Big Give' contestant Cameron with Manuel at an auto shop.

5 of 19
Since he can't give cash away, Cameron converts a chunk of his money into traveler's checks. Then, he stops at an auto body repair shop, where he pays the service bills of every car with an open ticket—a total of $8,000. Plus, he gives $500 to each of the men working in the shop.

While he's there, Cameron meets a customer whose bill he is paying off, as well as the man's son, Manuel.

"Nobody has ever done that for us," Manuel says. "This is the best day of my life."

The spirit of giving is in the air when Oscar, an employee at the shop, agrees to pay for every oil change that comes in the next day. "We'll definitely try and pass it on!"
