Yogurt ain't got no milk

The other day I was heading into a frozen yogurt shop when this really rather attractive woman in her early 20s came walking out with a double scoop. I smiled in her direction and she gave me the whole "lip snarl, rolling eyes of disgust" look. I couldn't help it, I yelled, "Hey! I was smiling at the yogurt. But from the look of that training bra you've got on, the yogurt ain't the only thing that's lactose free around here."
