Episode begins with Rigby reading a comic book on the couch)
Rigby: Oh this is so awesome!
(Mordecai walks into the lving room)
Mordecai: Hey dude, what are you reading?
Mordecai: That cheezy superhero?
Rigby: He's not cheezy! He's one of the greatest superheros ever!
Mordecai: Whatever. Hey, what's on the back of that?
(Turns around the comic book to the back of it and sees an ad)
Rigby: (Reading the ad) "You're a loser if you don't buy the most incredible, awesome, radical machine ever! This machine is one of a kind and its only around for a limited time, so order now!" Dude, I have to get that!
(Calls the phone number on the ad and screen goes to the next day when the machine arrives)
Rigby: Yes! My machine is here! I can't wait to prank Muscle Man once im invisible. (laughs)
(Benson walks into the room as soon as Rigby turns on the machine and they both get zapped which causes a little explosion and the machine is destroyed)
Mordecai and Skips: What happened?!
Benson: How should I know? I just walked in here and i got zapped.
Skips: Benson? Is that you?
Benson: What do you mean?!
Skips: Uh look.
(Gets a mirror and gives it to Benson. He looks at the mirror and its revealed that Benson is in Rigby's body and he drops the mirror to the floor)
Benson: Ah! What happened to me?!
Rigby: (wakes up) Aw man, im not invisible.
Mordecai: Dude, you better look at the mirror.
(Gets the mirror off the ground and its revealed that Rigby is in Benson's body)
Rigby: Ah! What the heck?! The ad said that it was a invisibility machine, not a body switching machine!
Benson: Well this is just great! This is all your fault!
Rigby: My fault?! Its the stupid ad's fault!
Benson: I wish I was in my body so I can punch you so hard!
Skips: Hey, stop it you two. Look, ill try to fix the machine but for now, you just have to deal with your new bodies.
Rigby and Benson: Fine.
(Pops comes in the room)
Pops: What happened here?
Benson: Rigby bought a machine off of the back of a comic book and it exploded.
Pops: Rigby, why do you sound like Benson? I guess you're getting better at your impersonations.
Benson: Pops, it is me, Benson.
Rigby: And now we switch bodies but there's no way to be back to normal because the machine blew up. Hey Benson, can I have a gumball?
Benson: NO! That's just wrong!
Rigby: Aw come on! You know I like gumballs!
Benson: Yeah but not ones that come out of me!
Mordecai: Look, how about Pops takes Rigby and i'll take Benson so no more fights will happen. Is that ok with you?
Rigby and Benson: Ok.
(Scene cuts to Mordecai and Benson in the golf cart)
Benson: Ok, so Rigby's legs aren't the greatest when it comes to driving things.
Mordecai: Yeah, that's why I do most of the driving.
Benson: So where do you wanna go?
Mordecai: The Coffee Shop, I need some coffee.
Benson: Yeah me too.
(They pull up to the coffee shop, they go in and Benson struggles to get onto a chair)
Benson: Man, Rigby's legs are hard to adjust to.
Mordecai: Dont worry dude. The machine will be fixed soon.
(Margaret and Eileen walk up to them)
Eileen: Hi Rigby. You look nice as always.
Benson: Um, thanks.
Margaret: Rigby, are you sick or something because your voice is deeper now.
Benson: Well um, im not Rigby, its me Benson.
Margaret and Eileen: Benson! What happened to you and Rigby?!
Mordecai: Him and Rigby got zapped by a body switching machine that Rigby bought off of a back of a comic book and now Benson is in Rigby's body and Rigby is in Benson's body.
Eileen: That's terrible!
Benson: I'm just worried about what Rigby is doing with my body right now.
(Scene goes to Rigby and Pops walking in the park)
Rigby: Ugh, this blows!
Pops: And why is that?
Rigby: Well, I like gumballs but I can't have one so I must resist my urge to have one.
Pops: Oh, I see. Well don't worry, Skips will fix that machine soon.
Rigby: I hope so because I don't wanna know what happens when I need to go.
(Scene goes back to the Coffee Shop)
Eileen: Well how are you gonna switch back if the machine exploded?
Mordecai: Skips is fixing it. He should be done soon.
Skips: (on walkie talkie) Mordecai, Benson, are you there?
Benson: Skips, did you fix it? Because I'm tired of being Rigby!
Skips: Calm down. Yes I fixed it and I just told Pops and Rigby and they'll be here in a bit.
Mordecai: Ok, we'll be there. Come on let's go.
Margaret and Eileen: Bye guys. Good luck.
(Scene goes to the guys at the house)
Mordecai, Rigby, Pops, and Benson: We're here!
Skips: Great. So Benson and Rigby, just put these on your head.
(Gives them helmets connected to the machine and they put them on their heads)
Rigby: Hey, will this hurt?
Skips: Let's find out.
(Pulls the switch and a shock wave can be seen coming from the machine to their helmets as they are getting zapped and yell)
Skips: Guys, are you ok?
(Benson and Rigby get up and look at Skips and it's revealed that their eyes are all white)

Benson and Rigby: (evilly) You tell us!
(They try to choke Skips)
Mordecai and Pops: Skips!
(They run over to Skips, Benson and Rigby and they pull Skips away from Benson and Rigby's grasp)
Mordecai: Dude, are you ok?!
Pops: What's wrong with them?!
Skips: Oh no, I think the machine malfunctioned and turned them evil!
Mordecai: Of course! So how do we turn them back?!
Skips: Actually I dont know.
Mordecai: Man, I wish Margaret and Eileen were here to help us. Wait, Eileen! Skips, Pops, do either of you know Eileen and Audrey's phone numbers?
