There have been adventure books, movies and television shows for decades and while the formats change, they all have the same underlying motivation. Every genre has their own quirks and habits that people can make fun of.
For adventure, it could be over the top heroic characters, overly elaborate traps and situations and many many more. Humor has always been a part of adventure stories, but parodies of these stories are just as prevalent. Austin Powers parodied the countless James Bond and other spy films in several films.
We watched as Dr. Evil complain about needing sharks with laser beams as he strokes his naked cat. Top Secret starred Val Kilmer as a rock star turned spy and included one of the last performances of Peter Cushing as a man that spoke backwards. I also have to mention the character of Chocolate Mousse.
The adage goes that imitation is the sincerest form of flattery, but they have never seen Cannibal Women in the Avocado Jungle of Death. We can make fun of characters like Allan Quartermain in movies like Allan Quartermain and the Lost City of Gold. Sure, these stories all make fun of beloved adventure characters, but they are funny and are meant to be an homage to classic adventure books and shows.
