Q: How many aerobics instructors does it take to change a lightbulb ?

Q: How many Einsteins does it take to change a lightbulb?
A: That depends on the speed of the changer, and the mass of the bulb. Or vice versa, of course. Then it just might be easier to leave the bulb alone and change the room. It’s all relative.
