An Eskimo is fishing on the Polar ice pack at a time when there is sunshine 23hrs per day. After 18 hours his bum is numb with cold, so he packs up his catch and heads back to the igloo. He hangs up his sealskin coat, and sits down to tuck into his seal steak when his wife says:

“Ingit”

“What?”, he says without changing his expression.

“I’ve got some news for you.”

“What?”, he says through clenched teeth.

“Your mother-in-law’s slipped on the ice, and broken her hip.”

Again his expression doesn’t change, he picks up a frozen herring, reaches across the table, and smacks his wife on the side of her head with it.

“WHAT DID YOU DO THAT FOR?” she said, aghast, picking herself up off the floor.

“I’ve told you before, don’t make me laugh when I’ve got chapped lips!”
