Customer: “You don’t have much of a selection for ninetieth birthday parties.”

Me: “Not many people live that long. Most of our suppliers don’t carry anything past the sixtieth birthday decorations.”

Customer: “It’s all because of Obama, you know. With his health care system, they just put you out to pasture once you’re sixty-five, and that’s the end of you. He probably told everyone to stop selling things with eighty and ninety on it, so people won’t want to live as long.”
