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?

Peter why is Steve from Minecraft stealing his Popeyes chicken

Huh??

Is this a reference to some tv show or something?? (Sorry if repost)

What does this mean Peter?

Peter why the hell does everyone keep talking about this number?

Peter explain what trans people do with this

Please explain. Am I dumb?
