[TOMT][MOVIE/TV] Scene with two guys in a plane

I have a very VERY distinct memory of a scene in a movie/show (probably a comedy, or atleast comedic in this scene) where one guy is very scared of flying in a plane, so he somehow ends up with some type of sleeping pill I assume. Which he takes and then he wakes up and is glad and says it worked, however he discovers that the plane never actually took off. I also remember a few scenes previous where he storms off the plane because the flight attendant is explaining the safety things and he gets freaked out, if that helps. My mom and dad also agree they rmemeber but cant remember where its from!! Please help! 🙂
