"GENTLEMEN, BEHOLD!!!"
Dr. Weird motioned towards a portal.
"I have created a portal to another dimension!"
"Holy crap." Steve remarked.
"Holy crap indeed! As matter of fact," A cannon was rolled in all of a sudden. "LOAD THE CRAP CANNON!!! MWAHAHAHAHAHA-AAAAAAAAAAHAHAHAHAHAAAAAA!!!"
"DO NOT LOAD THAT CANNON AND FIRE IT INTO THE PORTAL!!!"
"..."
"..."
"..."
"Steve, what the hell have I told you about bringing guests?"
"Uh, Dr. Weird, I never seen this robot before."
"I AM THE CYBERNETIC GHOST OF CHRISTMAS PAST FROM THE FUTURE, AND I HAVE COME BACK IN TIME TO WARN YOU THAT THROWING SHIT INTO THAT UNIVERSE WILL CREATE CHAOS BEYOND CHAOS AND..."
As The Cybernetic Ghost of Christmas Past from the Future rambled on, Dr. Weird made a nodding motion towards Steve, who simply grabbed the screeching robot and threw him into the cannon as it spoke, right before firing him through the portal, sending the robot into the new world, Equestria.
"BOOM, SHAKA LAKA!!! HAHAHAHA... HAHAHAHAAAAAAA!!!"
"Yay, now what?"
"Isn't it obvi..."
The portal suddenly closed, leaving Dr. Weird to glare as Steve.
"Umm..." Steve backed away.
"Oh Steeeeve... where are you going?" Dr. Weird asked as he loaded a crossbow with a 'BLAMO!!!' brand firecracker, know to be banned in all the States of the USA, Canada, and even Mexico.
Naturally, The laboratory blew up, and the two were never heard of again until the next episode.
The End, as closure for how it happened.
