T-Rex: Dollars for sale! DOLLARS FOR SALE!
T-Rex: Dollars for sale, you guys!
T-Rex: Dollars for sale in an auction where everyone pays their highest bid, whether or not they win!
T-Rex: So when you bid 1 cent, Dromiceiomimus - FOR A PERFECTLY LEGITIMATE DOLLAR - you'll be getting a great deal AND you'll make a profit of 99 cents! But watch out, because if Utahraptor outbids you with 2 cents, then you could lose your penny! Remember: you have to pay your high bid either way.
Dromiceiomimus: So it's in my interest to outbid him with 3 cents: that way I can at least make a profit of 97 cents!
Utahraptor: But then I'll just outbid her with the exact same motivation!
T-Rex: True!
Utahraptor: But then - if Dromiceiomimus bids 98 cents, I'll bid 99. Then she has to decide whether to bid $1: if she doesn't, she loses 98 cents, but if she does, she'll break even. So she does, and I'm left with the choice of either losing my 99 cents, or of bidding $1.01 and then only losing 1 cent.
Off panel: So I bid more than the dollar is worth, just to minimize my losses! And it keeps going, and we both end up bankrupt! This is the worst ever auction, and I'm not bidding.
T-Rex: Would you say... "The only winning move is not to play?"
Off panel: No, I think that movie's been referenced enough lately
