Two Eskimos sitting, paddling along in a kayak,
when one felt a little chilly so he made a little pile of sticks and lit a fire in the craft.
His friend shouted at him to put it out, but the warning was ignored.
Unsurprisingly, the kayak sank quite quickly and finding themselves in the cold water, the second Eskimo whacked his idiot mate over the head with a now redundant paddle.
“Ouch!!” said the previously warm Eskimo, “what did you do that for?!?”
“Because, you idiot,” said the second Eskimo, “Don’t you know that you can’t have your kayak and heat it too??”
Three professors (a physicist, a chemist, and a statistician) are called in to see their dean.
Just as they arrive the dean is called out of his office, leaving the three professors there.
The professors see with alarm that there is a fire in the wastebasket.
The physicist says, “I know what to do! We must cool down the materials until their temperature is lower than the ignition temperature and then the fire will go out.”
The chemist says, “No! No! I know what to do! We must cut off the supply of oxygen so that the fire will go out due to lack of one of the reactants.”
While the physicist and chemist debate what course to take, they both are alarmed to see the statistician running around the room starting other fires.
They both scream, “What are you doing?!?”
“Trying to get an adequate sample size!”
