Friendship means never having to say you're sorry. Or hungry. Or anything, really, provided you're a Wookiee capable of flying a spaceship. Solo and Chewie's bond is based on an understanding deeper than words. It might also be almost entirely guesswork, there's only so many times Chewie isn't going to understand "shoot back at the guys shooting at us" before you kind of get the gist.
Right off the bat, any group of people that can make it to brunch together so consistently without a bunch of last-minute "Can't make it :(" texts, deserves the highest award for friendship imaginable. It doesn't matter how many times they made fun of/screwed over/kind of genuinely disliked each other every week. What matters is they withstood it all, and only partially out of necessity since there's no way anyone else could ever love these sociopaths.
Most friendships require at least a base level of commitment on an emotional and logistical level. Wayne and Garth are committed to nothing but having fun and making sure other people have fun, which only works if you're as cool as them.*
*You never are and never will be.
It's not often a friendship survives longer than the people in it, but becoming a zombie couldn't even stop Ed from wanting to chill with his pal every day. The final scene of the movie, showing Shaun and Zombie Ed sitting together video games just like the old times, is as warming as my casual spoilers are infuriating.
If Golden Girls' premise isn't the definition of "living the dream," then I don't know what is. Hey, we've all fantasized about living in a big, cool house with our closest friends and also we're hot old ladies, right? The girls have been through thick and thin together, and come out stronger for it every time. That is until that CBS spin-off. There's no coming back from that.
