Cool Bikes/Transcript

The episode begins with a video of Mordecai and Rigby getting a cart out of the garage that says Muskrat 5000. They go to it and wave at Skips and Pops cutting a hedge. They wave at them back. They stop at Cheezer's and order something. Then they see some girls whose car broke down and stop at the gas station and drop them off. Then they meet up with Muscle Man and High Five Ghost in their cart. They beat them in a race, then Mordecai pushes a Turbo Boost button and beats them. They meet up with girls, then go in a skateboarding competition. They grind the handrail and go skateboarding, doing tricks. Later Mordecai closes the garage door and walks away. The next day Benson checks the cart and sees that it broke down. He turns red.

Mordecai: Ready for some more kartin'?

Rigby: You know it!

(M&R gasp)

Mordecai: Aw, what?

Rigby: Where's the cart?

Benson: It's at the shop! After your little excursion yesterday your cart privileges have officially been revoked!

Mordecai: But these bikes are for little kids!
