A gentleman goes to an estate sale and notices that one of the items for sale is a large parrot.
He's always wanted a talking bird, so when it comes up for bid he offers $50.
The bidding proceeds hot and heavy with someone always bidding ten dollars more than he until the parrot is finally sold to him for $1,500.
When he goes to get the bird, he asks the auctioneer, "Can the bird talk?"
The auctioneer replied, "Who do you think was bidding against you?"
