Peter: Alright, guys, it's time to summary Mark 7.

Lois: So, what's it about?

Peter: Well, it starts off with some Pharisees and scribes from Jerusalem coming to see Jesus and asking why his disciples don't follow the traditional Jewish customs.

Stewie: *interrupts* You know, I don't think I've ever seen a Pharisee in an episode of Friends.

Cleveland: Yeah, and I don't think the scribes ever made a guest appearance on Seinfeld.

Peter: Moving on, Jesus answers that it's not what goes into a person's mouth that makes them unclean, it's what comes out of it. And then he proceeds to list a bunch of examples of sinful things that come out of our mouths, like murder, adultery, theft, etc.

Quagmire: *Chuckles* Hey, that's the same kind of stuff they say on the back of a shampoo bottle.

Peter: He also talks about how it's not the physical things that make us unclean, but rather our hearts. So, yeah. That's Mark 7.
