I knew about the uvula...had to look it up back in the early days of SNL, due to a skit they ran. Pretty funny one, too. IIRC, this skit was played by Chevy Chase (as the doctor) and Babs by Gilda Radner:
[ Doctor enters the living room ]
Doctor: Hello, I'm the doctor.
Sister: Hi.
Babs: That must be him! [ coughs ]
[ Doctor sits next to Babs on the couch ]
Doctor: I won't beat around the bush, Babs.
Babs: Is it bad?
Doctor: In a nutshell, your uvula is on the fritz. Which reminds me of a little joke. Knock knock!
Babs: Who's there?
Doctor: Babs' uvula.
Babs: Babs' uvula who?
Doctor: I don't know, Babs. But I do know this - you've really let your uvula go to the dogs.
Babs: Yes.. I have..
Sister: I'd like to share this with you, Sis. [ opens a greeting card ] "To Babs: It'll behoove ya', to care for your uvula! Love, Sis."
Babs: Boy, do I hear ya', Sis! From now on, it's strictly good, clean fun. For me and my uvula!
