And he's the one they say is a gentleman

I thought Agassi was better than this:

Using a rather unorthodox sales technique, the former tennis great managed to get $7,000 for a porcelain plate at a charity auction earlier this month in Taiwan.

"You pay more than $4,000, and I will show you a picture of my wife — on my phone — naked," Agassi told the crowd.

True to his word, Agassi gave highest bidder Franz Chen a peek at a photo on his phone while on stage at the auction.

Chen said Tuesday that the picture showed the naked back of a blond woman who may or may not have been Agassi's wife, Steffi Graf.
