This couple out on a date get a flat tire while driving along on a snowy
night.

They guy gets out to change the tire, but he doesn't have any gloves
so before long he gets back in the car with the job half-done, his hands
blue from the cold.

"Put your hands between my legs to warm them up," offers his gal.

So he
does, then gets out to finish the job. It's so cold, however, that he has
to come back one more time to warm his hands, again between her legs.

Finally, he finishes the job and gets back into the car, and is about to
put the keys into the ignition when she asks, "Aren't your ears cold?"
