(Brian and Stewie are in the bathroom, staring at the toilet)
Brian: How do you think it works?
Stewie: I have no idea.
Brian: Look, Lois told me I had to start using the toilet, and you're the one who's had potty-training, so I'm counting on you to help me.
Stewie: Alright, we're two intelligent guys, we can figure this out.

Brian: What's that big back part?
Stewie: (nervously) Maybe that's where the wizard lives who operates this thing. It would be wise not to anger him.
Brian: (reaching for the flush handle) I wonder what this thing is for.
Stewie: Brian! Be careful with that, we don't know what it does.
Brian: (sighs) Alright, here goes.
Stewie: Oh god, oh god, careful, careful, careful, careful!
(Brian flushes the toilet, they both run out of the bathroom, Stewie yelling and Brian barking)
