70-ish guy with a slow southern drawl: "A whale tail? You know what a whale tail is, right? It's the top piece of a woman's thong. You know, she's bending over a bit, and you see the top part. The whale tail."
Toothless, townie guy at the nearby bar (with a drink in his hand): "Hey man, you've been on the Internet, haven't you?"
