"The Grumpy Emperor" is a song from the episode "High Tea".
Austin: A zillion years...upon this throne...has tightened up...my funny bone. You can joke as far as the eye can see, but not one chuckle will you hear from me. I’m grumpy!
Uniqua, Pablo, Tyrone, and Tasha: You’re grumpy! You’re frowny and you’re frumpy!
Austin: I’m grumpy!
Uniqua, Pablo, Tyrone, and Tasha: You’re grumpy!
Austin: And this throne is hard and bumpy! You can jokey and hokey-pokey, but you won’t get a laugh, okey-dokey?
Tyrone: How about this? Is it funny to you?
Austin: I’ve seen it before, try something new!
Tasha: Have you ever seen such a funny dance?
Austin: That’s not funny, not a chance!
Pablo: Have a look at this funny face!
Austin: If that’s funny, I’m a Ming vase!
