All the functions go to a party. After some drinks and music, the party is really going, with one exception: ex is standing awkwardly by himself in a dark corner. After a while sin(x) notices this, and so he goes over to talk to his nonalgebraic buddy. “Hey ex,” says sin(x), “why don’t you come out here and mingle.”
“Mingle?” asks ex, suprised.
“Yeah, mingle!” says sin(x). “You know, get out there and integrate yourself!”
ex sighs heavily and asks, “What’s the point?”
I heard a version of this joke from Courtney Gibbons.
