I made a Monty Python and the Holy Grail/Super Mario Bros. mashup up years ago, too. I just went in a different direction.
That’s the thing about humor. You can take a similar premise and go in completely different directions. I actually did a write-up about that exact same topic four years ago and how the same premise does not necessarily mean the same joke. Not sure if that article is out of date now, but I don’t believe it is.
