What to say? This was a show about a group of six friends. There was Ross Gellar (a paleontologist), his sister Monica (a chef), a waitress named Rachel Green, a dumb actor named Joey Tribbiani, a kooky sort of hippie chick named Phoebe Buffay (Lisa Kudrow also played Ursula on Mad About You, and we eventually learned that she and Phoebe were twin sisters), and a sarcastic accountant (or something) named Chandler Bing. They all hung out a lot at a coffee shop called Central Perk. The show had a very peppy theme song, "I'll Be There For You" by the Rembrandts. The show was wildly popular and lasted 10 seasons. And there were any number of changes over the years in terms of romantic pairings and so forth. There was a great deal of stuff about Ross and Rachel (he had liked her for a long time, like since high school or something, but she didn't realize it; they did eventually have an on again/off again relationship, though). I don't really know what to tell you, it was just a really funny, bubbly show, but not real big on plot. But the characters were likable and the girls were cute. *shrug* So, whatever.
Oh, after it ended there was a spin-off called Joey, though that wasn't nearly as good and didn't last nearly as long.
