(A small black hole prepares to suck in Willie's mop.)
Groundskeeper Willie: (waking up) Huh? What? ARGH! No one takes Willie's mop! (The hole threatens to suck Willie into it.) Take the mop! Take the mop!
(The hole complies. Willie braces himself onto the chair where he had been sleeping on. The hole then starts to pull in the mop bucket, which Willie stops in anxiety with one hand.)
Homer: Lisa, do you have a stray dog down there?
Lisa: (panicked) Um, it's a lot worse than a stray dog.
Homer: TWO stray dogs?!
Lisa: It's a black hole.
Homer: That was gonna be my next guess.
Lisa: (apathetic) Are you sure your next guess wasn't THREE stray dogs?
