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

1: Two. Plus a portable phone, an Internet link and a copy of the "Bluffer's Guide to Changing Lightbulbs."

2: Two (of course) but it will take all week and when they're done the light bulb will do your homework, speak French and shine any colour you want from it.

3: Two, but the job never gets done --- they just keep arguing about who is supposed to do it and how it's supposed to be done!
