Lileks explains:

What’s this Bunco thing your wife does? It’s a hen party. They meet at different houses, roll the bones, eat, enjoy cold libations. It is the absolute antithesis of poker. In poker men sit in silence, studying their cards and the other players; in Bunco everyone is talking, and no one is paying attention to the game. You could film six men playing poker, and sixteen women playing Bunco, and you would learn everything you need to know about the difference between the sexes and the nature of each. By our games do we know ourselves.

Isn’t it illegal to write “hen party” in Minnesota?  And what would Lileks know of poker?  Even Peeps could fleece the fellow.  I doubt there’s a serious card player in the Gopher State.
