There were a physicist, a circus strong man, and a statistician marooned on a desert island. A box of canned food washes ashore, and the question is how to open the cans. The physicist suggests dropping them from the trees so that they break open. The strong man says thats too messy. Instead, he will rip the cans open with his bare hands. The statistician says thats still too messy, but he knows how to open the cans without making a mess. First, he says assume we have a can opener.
