A/N: This chapter is very heavily inspired by the Regular Show episode, "Prank Callers". It still involves the Tallest, but some of the ideas in this fanfic are based on that Regular Show episode.

Disclaimer: I don't own Red and Purple. The people at Viacom and Jhonen Vasquez own them.

Red glanced around the bridge of the Massive. No one was in sight. He smirked and hovered quietly over to the handle-shaped device apparently called a "phone" and picked it up. The crimson Tallest fingered the inferior device and giggled with eternal glee. Zim had sent them one from Earth, and as Purple threw it away, Red saved the device from its fiery death. After some more research, the smarter Tallest found some amazing uses for this Earth technology, such as the activity he was about to perform.

Prank calling.

His green talons flew across the ivory buttons, and as soon as a muffled electronic ringing was emitted from the phone, Red giggled with glee and put the phone to where his ear would be.

"Hello?" A deep male voice groaned from the other end of the line. The cherry colored Tallest chuckled.

"Be sure to pick up a call from…" He began before bawling out in laughter "JOE MAMA!" He screamed before hanging up and doubling over in laughter again. A few seconds later, he picked up the plastic calling device and the Tallest's fingers pushed some numbers on the phone pad once again. Once some unlucky victim picked up, Red responded with something along the lines of. "Please hold for a collect call from...JOE MAMA!", with fits of laughter in between words. Once he had his fill of torturing random humans, the fun really started. The brick colored Tallest snorted as he picked up the phone for what seemed like the millionth time that hour and giggled before dialing his next stooge.

555-131-3946.

Red giggled as the ringing began.

"WHO DARES CALL THE ALMIGHTY ZIIIIMMM?" The voice on the other end screamed in outrage.

"Hello Zim. Have you heard of anyone named..." The Tallest fell to the floor in amusement. "JOE MAMA?" He didn't bother hanging up and continued laughing at his antic.

"Who is this? Whoever you are...ZIM will track you down. Zim will find you and make you face a pain like you have never faced pain before..." An unhappy Zim ranted as Red began pounding the floor in laughter. Crawling back to a standing position, the scarlet Irken hung up the phone and wiped away the tears of joy that had sprung during his most recent prank call session.

"One last call." He whispered to himself, a grin plastered on his face. With the push of several buttons, the familiar ringing came once again, and the mischievous Tallest giggled as he waited for the recipient of the prank call to pick up.

"Hello. This is the pizza guy calling about the fifty pizzas you ordered." He snorted.

"That's great. Bring them over as soon as possible." A high-pitched male voice responded casually. Red stopped laughing.

"I said fifty pizzas, Purple." He reiterated.

"Yeah, that's what I ordered." The violet Tallest was the one chuckling now. "And a large bag of churros. Hurry it up, I'm getting really hungry." The ruby colored Tallest opened and closed his mouth in surprise.

"But…" he whispered.

"Ok, enough with the act Red. I know you're not the pizza guy." Purple chuckled.

"How?" Red exclaimed.

"It was easy. One, I can recognize your voice from a million miles away. Two, those videos you've been watching of people prank calling strangers, I'm the Prank Caller. Three, you suck at this stuff." The lavender Tallest explained.

"There is no way that's you. You're voice isn't that deep." The rubicund Irken exclaimed, slamming the phone back into its holder. " Lying little twerp." He grumbled under his breath, making his way back to his chamber.

"Hey, just be glad you aren't…JOE MAMMA!" Purple exclaimed as Red hovered by his room.

"SHUT UP!"
