My Mom

(Episode begins with Mordecai and Rigby leave the nursery, holding a lemon tree. Rigby ties the tree to the golf cart)

Mordecai: Dude, hurry up! Tie it down, we're gonna be late!

(Mordecai and Rigby jump inside the golf-cart and drive off. A car stops)

Rigby: Go, Go, Go! Take that street! (they make a sharp turn)

Mordecai: We're not gonna make it, we're not gonna make it!

(Meanwhile, and are standing around at the park. Benson checks his watch)

Benson: I knew it. I knew they'd be late.

Y/n: (murmurs) Come on guys hurry up.  

Mordecai: This is gonna be close.

(Y/n, Benson and Skips watch over the hill for Mordecai and Rigby, but they're not coming)

Benson: That's it.

(Y/n, Benson and Skips approach the cart before Mordecai and Rigby suddenly come up driving)

Mordecai: (gasps) Dude, we made it! Dude, we made it! (Mordecai and Rigby suddenly hit a rock, sending them out of control. They hit a lamppost, which the tree is lodged into. Mordecai tries to get it out, but the leaves fall out. Mordecai & Rigby pick up the broken tree anyway and show it to Y/n, Benson and Skips) Here's the lemon tree you asked us to pick up.

Rigby: Right on time. 

Y/n: Uh huh right on time, one problem though. THERE IS NO TREE LEFT!!!

(Y/n and Benson watches the sole lemon fall off the tree) 

Rigby: I think the guy sold us a lemon, know what I'm sayin'?

(Mordecai and Rigby snicker. Y/n looks at them with annoyed expression while Benson turns red, growls at them, upset and angry that they failed their job, and he's about to yell, but quickly calms down)

Benson: No. You know what? I blame myself. I should've known better than to trust you two morons with such a straightforward task. You obviously need more supervision. Y/n call them.

Y/n: (walks to the cart) You brought this on yourself guys.

Mordecai: (confused) Super-what-now?

Y/n: (picks up walkie-talkie on the golf cart) Muscle Man, Hi Five Ghost, get down here. I need you to help me watch over Mordecai and Rigby.

Muscle Man: (over microphone) We'll be right there bro.

Mordecai: What?

Rigby: No way! (drops the part of the tree he has onto the ground in anger after hearing their names) You guys can't stick us with Muscle Man and Hi Five. Those guys are turds! 

Mordecai: They have the combined intelligence of bread-mold. Come on, Benson. Give us one more chance. At least have Y/n only watch us. 

Benson: No more chances. I am sending Y/n too, but since you two always get him stuck in your messes so I'm having Muscle man and High five go with him too. So here what's going to happen, I'm sending you to the nursery to pick up another lemon tree. If you screw up again, I'll have Muscle Man and Hi Five supervise the next job with Y/n. Then the next job, and the next. (turns red) GET IT?!
