How mant dopers does it take to change a light bulb?

I note that no indication of the number of observers has been added - that it, those who VIEW the changing of the lightbulb but do not POST to comment on it.

“How many SDMB members does it take to talk about ‘How many SDMB members does it take to screw in a lightbulb’?”

The self-referential nature of this thread is really making my brain hurt. I think I like it.
