How many magicians does it take to change a light-bulb?

Thirty.

One to change the light-bulb, the other twenty-nine to tell the person next to them that they knew how it was done, but if they had done it they would have done it slightly differently, which of course would have been the best way to do it.

Oh, and the magician that did change it claimed it was his idea, but really it's in Tarbell Volume 5.
