When writing a Prolog program a while ago I stumbled across an old mailing list where someone posted the following joke. Q. "How many Prolog Programmers does it take to change a lightbulb?" A. No.

Can't resist, I will add https://en.wikipedia.org/wiki/Answer_set_programming programming on this.

Q. How many Answerset programmers does it take to change a lightbulb? A. {1}, {1,2}, {1,2,3}, {2,1}, {2,1,3}, {2,3,1}

I guess the down voter has not programmed in Prolog before to get the joke.
