What one would call "dad jokes" are a small part of the endless array of gags in the movie. From sniffing glue, to the queue to hit the anxious woman, the swordfighting when panic breaks out, speaking jive, blowing the automated pilot, the turkish prison bit - it's a relentless sequence of all possible types of humor.

Comedy doesn't get enough respect because "it's just laughs", but this shit is hard. To pack so many accomplished jokes in such a short movie is genius - particularly in 1974.
