Francis, the Bird Curator of the City Zoo, is in search of some new parrots for a display, so he goes to a bird auction. The auctioneer steps up and announces that the final bird for sale that day is an exceptionally beautiful, rare macaw, and that the bidding will start at $2,000.
Determined to win it, Francis bids immediately, only to hear a voice from somewhere else in the hall call out "$3,000!"
Miffed, Francis raises his bird to $4,000, only to hear that same voice call out "$5,000!"
Undeterred, Francis goes up to $6,000, only for that same voice again to shout out $7,000!"
And so the bidding goes on and on between Francis and his unseen opponent, before the later finally relents. Francis steps up to the auctioneer later that day to pay his $20,000 and claim his prize.
"That's the most expensive parrot I've ever bought," he confesses to the auctioneer as he starts to fill out the check. "I hope at the very least that he's a talker."
The auctioneer smirks slightly. "Of course he is. Exactly who did you think was bidding against you the whole time?"
