First time visiting this brewery and they have a weird system in the bathroom. Can someone explain?

Help me peeta

Petah is this just a recipe for a smoothie or something im confused

Help

Petah I don't get it

What are these pills?

Duhhhhh I don’t understand

I get the joke but who is this man?

pita what is he talking about

Petah ?

Why is it that so many obscure Family Guy characters explain the joke, but not Peter?
