I’d say Simpsons, because it has probably the largest base of useful quotes.
Ren and Stimpy.
No sir, I don’t like it.
Cling tenaciously to my buttocks!
CALL THE POLEEEEEECCCEEEEE!!!
Its Always Sunny in Philadelphia, it would be an easy transition
BE GONE FROM ME
I just wanna be pure
The Simpsons or similar.
It’s been running since forever. If you’re going to constrain my vocabulary, I’d rather have it as large as possible.
The Simpsons are a perfectly cromulent way to enbiggen your vocabulary.
My son is also named Bort
Arrested development! Not sure it would change my daily interactions.
I’ve made a huge mistake
Pulp Fiction. I can still say useful everyday phrases like “Well, let’s not start sucking each other’s dicks quite yet.”
I’m pretty sure nobody around me understands why I always say little KANGaroo so strangely.
And no, I don’t often have reasons to say that, but that doesn’t stop me from making my own.
Star wars. It wouldn’t change much
Community
EDIT: changing my answer to Taskmaster, if only so I can still say “all the information’s on the task”
Also: stopcockstopcock stop. Cock. Stopcock
Very handy and widely applicable.
Though you’d lose the equally useful “pop pop”.
You would gain “a lime!” but lose “hello, rich people?”
Did I meet these potatoes before?
I Think You Should Leave.
“Hey, nice shirt Kolanaki.”
“Thanks. It was $450 dollars because the pattern is so complicated.”
Anything can be made from these quotes.
Over the Garden Wall. It’s not terribly long, yet remains one of the most quotes shows in my family.
Psych, because I am a fan of delicious flavor. It wouldn’t change much because I already quote it a lot
Whose Line Is It Anyway?
Tapiooooca!
Backstreet boys!
I know this is hours later now but, as I am just now reading through winding down for my night, this is what I’m watching!
Ice hole.
Local station news program. I suspect that would cover the most broadly applicable things that you’ll need to deal with. Aside from local place names you’ll still be able to talk about national and international news, finance/taxes, medical situations, weather, sports and entertainment, food… You’d have decades worth of back catalog to access from. You’d probably be wanting for specifics on some super niche hobbies, but it’s hard to think of much that you’d be missing entirely from your available phrases.
Futurama. I don’t what I would do if I couldn’t tell people to bite my shiny metal ass.
I basically already do it with Futurama, to the great confusion of everyone around me.
Shut up and take my money!
“The Good Place” - you bet your fudging life!
Holy shirt balls!
