Chalkboard: I will not flush evidence

Couch: A repeat of the couch gag first seen on the season four episode "Lisa's First Word" where The Simpsons join in a showbiz extravaganza featuring chorus girls, fire-eaters, circus animals, jugglers on unicycles, and magicians.

Bart: Well, I found another one.
(Bart crosses off "warthog" on his animal watching sheet)
Lisa: Bart, you didn't see a warthog.
Bart: I'm looking at one right now.
Lisa: Mom, Bart implied that I was a warthog.
Marge: No one's a warthog.
Bart: What about him?
(Bart points to a warthog in the car)

Homer: The Simpsons are going to Africa.
Family: Yay!
(In Africa, two tribesmen dance around a fire. Suddenly, one of them stops)
Tribesman: What is it, N'gungo?
N'gungo: Evil is coming.
Tribesman: What shall we do, N'gungo?
N'gungo: (puts his mask on the other tribesman's head) You are N'gungo now!

Ms. Skinner: And you! Start over! I want everything in one bag.
Bag Boy: Yes, ma'am.
Ms. Skinner: But I don't want the bag to be heavy.
Bag Boy: I don't think that's possible...
Ms. Skinner: What are you, the "possible police"? Just do it!
