In Farnsworth's lab within Planet Express Pinkie Pie jumped out of a pink parabox on the floor next to a metal table with a pile of porno magazines on it.
"Wow, this must be a parallel universe!"
She noticed a glowing with green light sphere shaped metal device on a metal table across the room.
"Ooooh, what's that?" she bounced over to the device to pick it up. "What does this thing do?"
Just then Farnsworth walked in to gasp in horror seeing what Pinkie Pie was holding in her hooves.
"Don't touch that Doomsday device!" he shouted in a panic.
Startled Pinkie Pie lost her grip on the doomsday device, which then fell on the floor and exploded with a blinding flash of light.
"Oops, silly me."
"You idiot!" he shouted.
Suddenly the entire planet of Earth exploded in a fiery explosion, followed by a sphere of fiery explosions expanding at a rapid rate through space. It wasn't long till the expanding explosions reached Mars vaporizing it on contact.
The explosions continued to expand faster and faster until the galaxies and space itself is gone leaving only plain white emptiness and the doomsday device itself floating in nothing.
However after about five minutes of the universe being destroyed the doomsday device beeped, thus recreated the universe in a blinding flash of light.
"Whoa, that gave me a headache." said Pinkie Pie while rubbing her right hoof over her forehead.
"Luckily I gave it a fail-safe to recreate the universe." He stood up off the floor, then angrily spoke through gritted teeth while glaring at Pinkie Pie. "Just in case some idiot accidentally destroyed the universe."
"Sorry." she said sadly looking down at the floor.
"I forgive you. But you must go home now and think about what you did!"
"OK."
Pinkie Pie jumped back into the parabox.
