At Ginny&#x27;s a chicken clucks around a plywood board with numbers, as the crowd urges it on. A typical Sunday evening at Ginny&#x27;s Little Longhorn Saloon, in Austin, patrons were enjoying the bar&#x27;s weekly game of bingo. &quot;There you go!&quot; shouted Mr. Gelernter. Henny, a brown hen, was clucking around a plywood board with a grid of numbers on it. The game hinged on where she pooped. This sport is known in polite company as chicken-poop bingo. There&#x27;s also a version that involves cows.
