(Y/n) picks it up. A prank caller is on the other end. "Hello?" She asked. "Loser says what!" The person said. "Who is this?" (Y/n) asked. "Loser says what!" They said again. "I know what you're trying to do. I'm not going to say "what." (Y/n) then realizes that she just did and face palms. The man laughs. "You're a loser! You loserhead! I hate you!" (Y/n) hangs up. "Dude, I think someone just prank called us." She said. "Ah, yeah. It was probably Kevin." No Rules Man points to the phone booth. Kevin laughs hysterically before the phone booth blasts off like a rocket.
"Huh, I didn't know Doctor Who lived here." (Y/n) said sarcastically. "Oh man, you guys can make prank calls down here?" Rigby asked. "You still don't get it, do you? Down here, you can do..." No Rules Man floats up to the air. "...whatever you want." He said. "Whoaaaaaaaahhhhhh." The trio said, they, too, float up to the air. "Dudes, in Benson's face! Living without rules is awesome!" Rigby said.
"Yeah it is!" Mordecai said. The trio laugh. "No rules! No rules! No rules! No rules!" They chanted. No Rules Man laughs. "That's right, no rules at all." He points. "Hey, look over there!" The trio look off in distance, then, the No Rules Man punches (Y/n). "Ow!" She turns to glare at him. "What the heck, man?" Mordecai asked. "Dude! He just took your wallet!" Rigby said to (Y/n). No Rules Man has her wallet. "Dude, give it back!" (Y/n) said. "Why? There's no rule that says I can't take other people's stuff." He replied.
"He's right, dudes." The trio recoil in fear at seeing an old Mordecai. "Oh, man! I used to be so cool-looking!" He pats Mordecai's hair. "Wow, you're totally going to miss that. You know what else you're going to miss?" He points to (Y/n). "Her. Enjoy her while you got her, you know what I'm saying?" Rigby and (Y/n) look at each with fear and concern. "What?! That better not be some kind of foreshowing!" (Y/n) shouted. "Yeah, what does that mean?!" Rigby panicked. "Oh, uh, nothing, dude." old Mordecai said. "Dude! How is this even happening?" Mordecai asked. "Because there's no rule that says it can't! From your future to your past, anyone can join the party."
No Rules Man said. Suddenly unicorns drive up from below. "Unicorns?!" Mordecai shouted. "Not these jerks again!" (Y/n) shouted. "They're supposed to be dead!" Rigby shouted. "Check it, bros! It's those three jerkbags that blew us up!" The 1st unicorn said. "You gotta listen to us, man! These guys are seriously bad news! You gotta get rid of them!" (Y/n) shouted. "Did you just tell me what to do?! You just told me what to do! Hey, they just told me what to do!" No Rules Man shouted. Shock comes to some punks, Kevin, and the unicorns.
"They're telling people what do to?!" The 1st unicorn asked. "Oh, no way, bro! Get 'em!" The 2nd one said. The unicorn's car drives up into the sky and runs (Y/n), Mordecais and Rigby over, sending them to the ground. They get up as the car turns around to chase them, running the old Mordecai over. The trio duck for cover as the punk truck comes up. The punks give the trio punchies as Kevin's phonebooth comes zooming towards them, which they duck under before a giant RPS hand comes to try to crush the trio. "Hey, you gotta get us outta here, man!" Rigby shouted. "This guy ain't gotta do jack, amigo! I can't believe how lame you guys turned out! I thought you were cool!" Everyone else comes up. "Us lame?! You're the one who turned out to be lame you big jerk!" (Y/n) shouted. "I hate to admit this, but I miss Benson and his stupid rules!" Rigby shouted.
"Wait! Yo! No Rules Guy! You do have at least one rule down here. You have a rule against rules." (Y/n) said. "There's no rule against rules." No Rules Man said. "That's all I needed to hear." (Y/n) raises her hand to make the rule book appear in midair. "Bros! Bros! Bros! Bros! Bros! Bros! Bros! Bros!" As the unicorns drive up, (Y/n) flips through the book. "Rule #37: No unicorns!" She shouted.
Unicorns explode into neon blue goo. "Rule #72: No rock-paper-scissors!" The giant hand explodes. "No punchies!" The punchie-playing punks blow up. "And no prank calls!" Rigby shouted. Kevin explodes into neon blue goo before the phone booth vanishes as well. "Stop! Just stop it! You guys have no idea what-" "AAAAAGGGHHH!" Rigby tackles No Rules Man, then, Mordecai jumps in and pins him to the ground. "Show us the way out of here!" He shouted.
"There's no rule that says I have to!" No Rules Man shouted. (Y/n) then walks up. "There's also no rule that says I can't point this laser pointer in your only good eye!" She prepares to do it. "Okay, okay! I'll take you out!" Later on the trio go back to the house. In Benson's office, he's writing something up as Mordecai drops the rule book on the table. "There. We signed off on all your rules, Benson." He said. "Well, well, well. Wasn't so easy living without rules, was it?" Benson opens the book.
"Wait a minute. One of these rules is missing." He said. "Oh, no. Which one?" Rigby asked. "I don't know, there's over a hundred of these things!" Benson shouted. "Well, then, how do you know it's missing?" (Y/n) asked. "Because somebody RIPPED IT OUT!!" Benson shouted. "That's crazy. I wonder which one it is." Mordecai said. Back at No Rules World, The No Rules Man is playing Karate Choppers, all by himself. "Hmph. Hmph. I don't need those guys, I can play video games by myself." The ripped page falls onto his lap. It is Rule #117: No Video Games. "NOOOOOOOOOO!!!!!!!" The No Rules Man, as well as everything else explodes, leaving the No Rules World into nothing but a barren wasteland.
