What's a Hiney Shot?

Friday night we were riding down the Boulevard. Our friends John and Gerri were in the backseat. Mike, who was driving, said, "What's a hiney shot?"

This had nothing to do with the subject we were discussing, but to humor him I said, " I guess it's a shot given in your derriere."

"Well," he said, "why would Walgreen be advertising that they are giving shots in the rear end?"

At this point, we all turned around and looked at the Walgreen kiosk. It said "HINI shots available here." We all started laughing when we realized that it meant H1N1 shots not hiney shots.
