"Have you ever been kissing someone, and one of you has snot that's whistling? It takes your mind off the sex, because it requires a three-step solution.

First of all, you have to figure out whose nose it's in. Then you have to determine which nostril. Finally, someone has to dig in there and, if not remove it completely, at least push it to one side so it doesn't whistle anymore.

By the way, during all this activity, the man usually loses his hard-on."
