Lucy & Ethel (I Love Lucy)

If Lucy & Ethel from 'I Love Lucy' aren't top of your Greatest Iconic TV Duos list, you might need to check your pulse—or your nostalgia settings! These two are the queens of the 'oops' and masters of the 'what now?' Spawning a million 'best friend goals' before hashtags were a thing, they're the blueprint for every TV duo that's had us in stitches since. Watching them try to one-up each other is like watching your two favorite aunts at a family reunion: endlessly entertaining and slightly concerning.
