Rigby: Dude, come on! I got to show you something.
(Mordecai wakes up and goes downstairs to the living room)
Mordecai: (sighs) What?
Rigby: Guess this: there is a new video game based on the Strong John series called Strong Johns 4: Strong Johns vs Wreck-It-Ralph and Fit-It Felix.
Mordecai: What's so great about a new video game? You know these people are tricking you into buying stuff so that you could waste your money on some useless products.
RIgby: Oh, yeah? That's easy for you to say. Last time you wasted your money on some dumb colongne that attracted unicorns. DRUNK unicorns.
Mordecai: They are not drunk.
Rigby: Whatever, bro.
Mordecai: Dude, I thought it would hot chicks. Besides, that drag racing contest already brought them dead!
Rigby: Yeahhuh they did.
