Dr Joan Bushwell: Every day I get up at 5:30, watch the chimps, eat a quick lunch of roots and water, then more chimpwatching. After dark, I come home and think about chimps until it's time for bed.
Homer: You must be the most boring woman on Earth!
Kitenge: Good night. Don't let the bed bugs paralyze.
Marge Simpson: Homer, did you remember to tip Kitenge?
Kitenge: [from outside the door] No, he did not.
[when The Simpsons are on holiday in Africa, Bart marks that he has seen a warthog to his animal card]
Lisa: Hey! You didn't see a warthog!
Bart: I'm looking at one right now.
Lisa: Mom! Bart implied I was a warthog!
Marge: Nobody's a warthog!
Bart: What about him?
[Lisa notices that there is actually a warthog right next to him]
Homer: Olive oil? Asparagus? If your mother wasn't so fancy, we could just shop at the gas station like normal people.
[after discovering Dr. Bushnell's illegal diamond mining operation, Lisa examines the scientist's research]
Lisa: These are just pictures of monkeys from famous movies! This is disgraceful, Doctor!
Dr. Bushwell: All right! So I snapped! You don't understand the crushing loneliness and greed.
Kitenge: Night, night. Sleep tight. Don't let the bedbugs paralyze.
