(Homer warms up his voice before a performance.)
Homer: (Singing) D'oh, d'oh, d'oh, d'oh, d'oh, d'oh, d'oh, d'oh. Woo, woo, woo, woo, woo, woo-hoo. Stu, stu, stu, stu-pid Flanders.
(Ned Flanders peeks in the dressing room.)
Ned Flanders: Why the crescendo, my dear, old friend-o?
Homer: (Singing) Get lost you waste of a mustache.
Ned Flanders: Okily-dokily.
(Placido Domingo towel snaps Homer in the locker room after a performance.)
Placido Domingo: Nice set, Homer. That was a hot one.
Homer: Wow, praise from Placido Domingo.
Placido Domingo: Just call me P-Dingo.
Homer: Ehh, I'll think about it.
Dr. Hibbert: Homer, you have a mild back sprain. And you also ingested a dangerous quantity of grave dirt.
Homer: Well, you're always telling me I should eat more dirt.
Dr. Hibbert: Not dirt, vegetables!
Homer: Which grow in what?
(In the dressing room after Homer's first performance.)
Bart: Dad, you were great!
Lisa: And you contributed to our culture!
Homer:(Worried) Well, I didn't mean to.
Lisa: No, no. It's a good thing.
Homer: (Relieved) Oh, good. This makes up for me showing up drunk to the father-daughter dance.
Lisa: The dance isn't till next week.
Homer: Sorry, Lisa. Can't change the future.
