That's sad.
My daughter thinks Monty Python is hilarious and sings along with "Camelot" form Holy Grail.
My oldest daughter saw The Dark Crystal when it was still in theaters, Secret of NIMH when it was still new, and Princess Bride when it was still new. Quotes them all. Loves Monty Python and used to like Benny Hill.
In fact all of my kids quote Princess Bride, have some Monty Python familiarity, and pretty much all of us riff off of Eddie Izzard. Like you do.
Sadly, none of them can quote Firefly.
I guess my job's not done yet.
