This morning, Gary in our cantina posed me this riddle:

Gary: “Repeat after me: Slick, slick, slick.”
Me: “Slick, slick, slick”
Gary: “What does a cow drink?”
Me: “Milk. Wait. No it doesn’t. Bah.”

On my way home from work, I listened to Boing Boing’s first podcast (can’t find the link now), about the O’Reilly Mind Hacks book, explaining why Gary tricked me. Nice :)
