Three friends go on a skiing trip to the mountains. They rent all the equipment and hit the slopes.
But on their first day, the weather is just awful. It's windy and cold, and there's a blizzard coming in. They can barely see a few feet in front of them, and it's freezing.
They decide to call it a day and head back to the lodge for some hot cocoa. They strip off their ski gear and warm up by the fire.
After a while, one of the friends says, "You know, we should play a game to pass the time until the storm passes."
The other two friends agree, so they decide to play "20 questions." One friend thinks of something, and the others have to guess what it is by asking yes or no questions.
The first friend thinks of something small and furry. The other two start guessing: Is it a rabbit? Is it a squirrel? Is it a hamster?
After 19 questions, they still can't figure it out. Finally, the first friend says, "Okay, last question: Is it a moose?"
The other two friends burst out laughing. "A moose? How could it be a moose? Moose are huge! This thing is small and furry!"
The first friend just grins and says, "Well, the moose was wearing ski goggles!"
