The Young Ones
Almost anyone on Battlestar Galactica. There were maybe two reasonably functional relationships in that entire show, tops.
Howard and his mother on The Big Bang Theory.
Sheldon Cooper and anyone on The Big Bang Theory.
Ron Harris and Arthur Dietrich on Barney Miller.
Can’t believe I’m the first to mention Spock and McCoy. (Get a room, guys!)
Walter White and Jesse Pinkman.
Archie and Meathead.
Carrie and Brody on Homeland.
Everyone on Shameless (US).
Rick and Shane on The Walking Dead. I wish the producers had waited another season or two to divorce them.
I love her goodnight kiss from Caligula. “My body fascinates him… you’d think it would repulse him, wouldn’t you?”
Cheryl and Pam.
