I learned about Monty Python and Fawlty Towers through my dad. And we used to watch a bunch of other British comedy series as well like The Young Ones, Bottom, Monty Pythons Flying Circus, Mr Bean and Keeping Up Appearances.
Dad and I also used to watch The Simpsons along with my youngest brother and sister. Not much anymore though.
Dad does not understand Seinfeld however. Whenever it was/is on the TV he used to say "Do you find this funny?" in a perplexed manner. He thought it was awful. I don't share that mindset obviously. :-)
