A neighbor, who also happens to be a co-worker, is walking up and down the street with his two little kids, the older of whom is on a snazzy, shiny, new bike with training wheels.

Me: "Hey, that's a pretty cool bike! Did you get that for Christmas?"
Kid: "Noooo...."
Me: "Oh, it didn't come from Santa Claus?"
Kid: (looking at me like I'm a total moron) "No, it came from the store!"

OK then.
