How many mathematicians does it take to screw in a light bulb?

One. He gives it to six Californians, thereby reducing the problem to an earlier joke...

In earlier work, Wiener [1] has shown that one mathematician can change a light bulb.

If k mathematicians can change a light bulb, and if one more simply watches them do it, then k+1 mathematicians will have changed the light bulb.

Therefore, by induction, for all n in the positive integers, n mathematicians can change a light bulb.
