"Cold Hands" joke

Two young lovers go up to the mountains for a romantic winter
vacation. When they get there, the guy goes out to chop some wood.
When he gets back, he says, "Honey, my hands are freezing!"
She says, "Well, put them here between my thighs and that will warm
them up."
After lunch he goes back out to chop some more wood and comes back and
says again, "Man! My hands are really freezing!"
She says again, "Well, put them here between my thighs and warm them
up."
He does, and again that warms him up.
After dinner, he goes out one more time to chop some wood to get them
through the night. When he returns, he says again, "Honey, my hands
are really, really freezing!"
She looks at him and says, "For crying out loud, don't your ears ever
get cold?"
