Rigby: (looking at his program list) Alright, let's see now. Foreign language, check. Geology, check. All that's left is....Bam! Rigby (continued): Gym class! Once I pass this, I'll finally be able to graduate. Besides, any bozo can pass gym. Mordecai: Then why didn't you pass the first time? Rigby: I dunno. High school was a long time ago. Principal Dean: Alright, you little loafers. Listen up! Coach McCrackle will no longer be teaching here. Rigby: A substitute? This'll be easier than I thought. Hello, high school degree. Jablonski: Body check! Teenage Rigby: Jablonski, no- Jablonski: Set me up!
