Funny, but Stupid
As Henry Gibson's Nazi in the potted plants would have said. Seriously, who wouldn't have gone to "Lucinda, your niece?" or "Lucinda, your brother Leon's niece?" (in case of family weirdness) first?
I know that sometimes the jokes have to be set up, but this is as bad as Luanne's teacher writing "Chap 5, 6-7" instead of "Chaps 5-7" on the board.
