I keep seeing variations on this joke:
Q: How many Object-Oriented Programmers does it take to change a lightbulb?

A: You're still thinking procedurally. A properly designed light bulb object would inherit a change method from a generic light bulb class, so all you'd have to do is send a light-bulb-change message.
For a start, that's not funny.

For another thing, is it true to the spirit of proper O-O? Is it logical? Do we learn anything from this joke? I'm not thinking procedurally in asking that question, am I? The answer is, procedurally you would do "$light_bulb = ($light_bulb + 1)" or something, rather than, in O-O, "$light_bulb->change(1)". The question can't be wrong, only the answer.

Anyone got a better version?
