Pajama Jeans are one of those great products that seem completely ridiculous at first, but the more you see their ads the more they bore deep into your brain and won’t ever leave. The entire concept is silly, but the fact that people must be buying them in order for them to continue advertising is plain absurd.
BILLY: Because bluejeans weren't casual enough?
RICK: They're great! I can get wear them all day and then to bed. When I get up the next day, I don't even have to change!
BILLY: You look like a girl. Take those off.
RICK: They're like a good mullet--multipurpose!
JIMMY: I think maybe they're cutting off the blood from his brain.
