A physicist, a chemist, and a statistician are called into the dean’s office at a university. But the dean is called out of the office leaving the three researchers by themselves. Suddenly, a fire ignites in the wastepaper basket.

The physicist quickly says “I got this. All we have to do is lower the temperature of the material until it is below the ignition temperature.”

The Chemist says “No, I’ve got a better idea. Lets take away the fire’s oxygen supply so it doesn’t have one of its reactants.”

As they are arguing the statistician starts running around the room setting everything on fire. The other men yell at him “What are you doing?!”

He replies “I’m just trying to get an adequate sample size.”
