On the topic of poop, I can't recall anything after the first hour or so...
"You taught him to sign?"
- Yeah but all he knows is, "where should I throw this?"
- You know it's not very safe for me to ride back there. Also uncomfortable. And very demeaning for an ape of my intelligence. OK FINE, I pooped back there this morning, happy?
- First thing's first, find a good flingin' pirch.
- I must admit I didn't think too much of Chimpey Dufresne the first time I laid eyes on him. He looked like the most lightly thrown poo would blow him over.
- My only regret is regularly pooping my expensive pants!
- (Reading a screen) Jacobs... flings... his... own... HEY!
- Hmm, if only there were something I could drop on him to get back at him... but what?
EDIT: As a poop joke connoisseur, I can tell you that this is still an above average number of poop jokes for an episode of Rifftrax. If your thirst was not quenched, pick up Indiana Jones 4.
