From Lloyd Grove:

"Put your freaking, f--g hand down! You! Who keeps waving in the air!" charity auctioneer Donald Trump ordered a dinner guest at Chelsea Piers during Monday night's fund-raiser benefiting the c for autistic children and honoring Katie Couric and Judith Giuliani.

"I'm kidding," Trump belatedly added as the bidding stalled on a trip to Costa Rica.

But moments later when a Verdura bracelet came up, Trump was at it again -- bidding on behalf of bachelor financier Teddy Forstmann. "Okay, $45,000 for Teddy. When you negotiate for someone else, who gives a s--?"

Maybe The Donald's mouth could use an industrial-strength scrubber. Then there's the way he treated the portly guy who placed the winning $16,000 bid on the Costa Rica vacation.

After inviting the poor fellow onstage, Trump zinged him: "You see, he wants to catch Montezuma's revenge and lose 50 or 60 pounds!" Ouch.
