In this pun on the phrase one trick pony, we see a contract bridge group holding their cards. One player asks her partner (who is a pony), "What is your bid?" The pony looks a bit distressed, because we can assume he can only make one trick.
There is no horsing around when you’re bidding in bridge! (Dedicated to my former bridge group, Team Cheatnasium vs Team Vulture)
