Dropped Your Wallet

Two fishermen were out on the lake when one of them dropped his wallet. As they watched the wallet float down to the depths of the lake, a carp came along and snatched up the wallet. Soon came another carp who stole it away and then a third joined in. Remarked one of the fisherman, "That's the first time I've ever seen carp-to-carp walleting."
