Airplane

When compiling a list of the greatest comedies of all time it's hard to ignore Airplane.  Crafted as an almost scene for scene parody of the 1957 movie Zero Hour! (how did that end up on their radar?) the movie was filmed for $3.5 million and ended up making $83.4 million, making it insanely profitable.  It also rescued the careers of a lot of people and helped launch a few others (Jonathan Banks a.k.s. Mike from Breaking Bad played air traffic controller Gunderson).  The original cut was 115 minutes long which at the time was considered an epic length.  It was finally cut to 88 minutes.  

Oddly enough Leslie Nielson used to sell portable fart noise machine and played with it constantly during the filming of the movie.  

Anyone with a sense of humor is going to love these Airplane t-shirts, all officially licensed and available in sizes up to 7XL.
