If you give Deadpool a lightsaber, he’s going to ask for another lightsaber.
When you give him the second lightsaber, he’ll probably ask you for a red Sith robe.
When he’s finished dressing up, he’ll ask for the largest mirror in your house.
Then he’ll want to pose dramatically in front your largest mirror, as his robe billows behind him, to make sure he looks as badass as possible.
When he looks into the mirror, he might notice an intruder, so he’ll probably ask for his bag o’ goodies.
When he is finished giving the intruder a taste of his goodies, he’ll want a list of new marks to assassinate.
He’ll start killing (while having you drive him around the city). He might get carried away and destroy every piece of property in the tri-state area.
He may even end up killing people who were never on the contract list to begin with!
When he’s done, he’ll probably want to go back to your place and eat some chimichangas.
You’ll have to fix up a large plate of chimichangas for him with a six pack of beer and chips to go with it.
He’ll dig in, and make himself comfortable on your couch, and place his gore stained boots onto your antique mahogany coffee table.
He’ll probably ask you to put on a movie.
So, you’ll get your DVD collection, and pick out some of your favorites (Neverending Story, Princess Mononoke, The Fault in Our Stars, etc) and he’ll ask to see your Monty Python collection.
As he watches Monty Python and the Holy Grail, he’ll get so excited that he’ll want to make a movie of his own. You’ll remind him that he already did but then he will stick a chimichanga down your throat before asking for a video camera and a black beret.
He’ll film a movie.
When the movie is finished, he’ll want to burn a copy of it onto a disc and sign it with a Sharpie. He will then save it later to auction off on ebay.
Then he’ll want to upload the movie onto Youtube.
Which means he’ll need your computer.
He’ll upload his movie and watch as the view count goes up with each refresh.
Staring at the glowing screen will remind him that he’s badass.
So, he’ll ask for a lightsaber.
And chances are if he asks for one lightsaber, he’s going to want another one to go with it.
