On a recent episode of Shark Tank, inventor Cactus Jack was faced with two offers that would yield him $180,000 for his product, a device that makes it easier for heavy people to do push-ups.

Barbara Corcoran, taken with this big guy with a big personality, offered to give him the cash -- provided he lose 30 pounds. Otherwise, she said, who could take a weight-loss guru seriously? If he didn't lose the weight, he'd lose the deal. (Watch back episodes of the ABC show at this link.)

"There's no way in hell he's losing 30 pounds," kvetched fellow Shark Kevin O'Leary after Cactus Jack had left the room. "The 30 pounds is gonna keep it off the table forever."

Flash forward. Months later, Cactus Jack has flown to New York City from Iowa to meet with Corcoran and hash out the future of his business. Critical to the next stage is the big test: Has he lost the weight contingent to the deal?

Corcoran invited WalletPop to her penthouse office for the big moment. At stake: A comically large novelty check made out for $180,000, and potential infomercial involvement by TV impresario Kevin Harrington.

Was this medical check-up a photo op for the media? Of course it was, but it was fun. And did this larger-than-life guy prove Kevin "Mr. Burns" O'Leary wrong? Watch and see.

It was a moment worth $6,000 a pound.
