Here's an idea I've had for awhile, so please keep an opened mind.

The Mutant Movie
Prologue: The First Screening
It was a bright shiny day at 21st Century Fox studios. A car drove up to the gate guard.
"Hello, I'm Victor." Victor Creed said.
"I'm Wade." Wade Wilson added. "We're here to heckle The Mutant Movie.
"Gentlemen, that's straight ahead." The guard said. "Private Screening Room B."
"Private screening?" Victor asked.
"Yeah, they're afraid to show it in public." Wade replied as the two laughed.
They then drove onwards.
"Look at this place." Victor said. "What a dump."
"Especially since this is just a very poorly disguised parody of 20th Century Fox Studios." Wade added.
"What?" Victor asked.
"Nothing." Wade countered.

In the screening room, Jean Grey, one of the stars of the movie, was talking to some of her friends.
"Yeah, I know, it was great." Jean said with a smile as a large man named Fred Dukes appeared.
"Hey lady, is this seat taken?" Fred asked as he pulled the seats next to Jean away.
"Hey you, bring that back!" Jean shouted out.
"Oh man, I'm so nervous." Bobby Drake, another star said. "If I'm not funny, I won't be able to live with myself."
"Well then, you'll have to get another apartment, won't you?" Hank McCoy said with a smile. As Bobby smiled too at the joke.
"You know, I heard that this movie is dynamite." Remy LeBeau, a supporting actor in the film, said with a smile.
"Popcorn!" A supporting actor named Todd Tolansky said. "Fresh organic popcorn, only a buck."
"Oh honey, buy me some, please?" Emma Frost asked her boyfriend, Warren Worthington.
"Oh sure." Warren said. "Nothing's too good for my woman."
"Woman!" The semi-unstable John Allerdyce called out. "Woman!"
"Oh, you had to set him off, didn't you?" Emma asked.
"Sorry." Warren said.
"Well I like the movie fine, so far." Victor said.
"It hasn't started yet." Wade pointed out.
"That's what I like about it." Victor added with a smirk as the two laughed.
Scott Summers, the host for the screening and one of the stars of the film walked down as he was stopped by Nick Fury.
"Scott, does this film have culturally redeeming values?" Fury asked.
"I certainly hope so, Nick." Scott said before turning to his girlfriend and co-star. "Hey Jean."
"Hey Scott." Jean said. "I tried to save you a seat, but someone took it."
"No worries." Scott said as he got in front of everybody. "Okay everyone, welcome to the first screening of the Mutant Movie."
Everyone cheered.
"Now before we begin, I'd like to give thanks to everyone who made this film possible. Starting with the hair dressers to the costume designers and-"
"Scott, I don't think speeches are necessary." Jean pointed out. "We can just watch the credits at the end. Roll the film."
"Well I just wanted to thank-" Scott began when John began shouting.
"ROLL THE BLOODY FILM!"
"Okay, okay." Scott said calmly. "Roll the film!"
Scott then sat down to his younger brother, Alex, who had blond hair and brown eyes.
"Hey Scott, is this how you guys really got started?" Alex asked.
"Well it's approximately what happened." Scott said with a smile as they turned to the screen.
I know some of you will be angry with me mixing Muppets and Mutants, but I figured on giving it a shot, so don't be afraid to tell me what you think. Just please keep it PG.
