I think you're right, LadyJ, but I am also fairly sure that User Friendly stole it from one of those emails that does the rounds featuring amusing tech support calls. Don't quote me, though.
That's why I said, "or some such". I'm not against joke-recycling, but in a voting situation, I'll go with something original and funny over something recycled and funny.
The interesting thing is that if you want to be picky, Chicka's is recycled, too, since she says she took it from a real life conversation. Still, borrowing from life has more merit than borrowing from other comics, IMHO.
I am a delicate ****ing flower.
