From its opening credits to its very special Ferris Bueller's Day Off riff at the end, director Tim Miller's Deadpool is easily one of the funniest comic book movies that we've seen to date. And while a great deal of that comes from the physical humor on display, most of the credit belongs to the dialogue. From the script by Rhett Reese and Paul Wernick, to improv done by the movie's stars, the blockbuster is absolutely jam-packed with hilarious one-liners that have been causing audiences to practically fall out of their seats laughing.
