Parrot at Auction
One day David went to an auction. While he was there, he bid for a parrot. David really wanted this bird, so he got caught up and thoroughly involved in the bidding. He kept on bidding, but kept getting outbid, so he bid higher and higher and higher.

Finally, after he had bid much more than he had intended, David won the bid; the parrot was his at last.

As he was paying for the parrot, he said to the auctioneer, "I hope this parrot can talk. I would hate to have paid this much for it, only to find out that he can't talk!"

"Don't worry." said the auctioneer, "He can talk. Who do you think kept bidding against you?"
