What you see in the picture above is a genuine spit-take caused by an improvised line that never appeared in the movie Mean Girls. It should have.
Every movie has tons of footage of flubbed lines and giggles that often get released after the film peaks. These compilations can be a treasure trove of improvised lines, jokes, and pranks that are funnier than anything in the final cut. Some of those clips weren't used because they caused the actors to break character, which we really don't mind when we go to see a comedy. Or an improvised joke could have changed the arc of the scene or even the entire movie plot. Still, it's well worth it to go back and watch these outtakes and wonder what might have been. Cracked found the best jokes in nine movies and TV shows that never made the final cut that should have been left in, with all the necessary videos to see them.
