Yeah, there was a good year long stretch, this was maybe 2005 or 2006, where I tuned in to the reruns every single night and caught up on the entire series. So good. I hated it when I was little because it beat Seinfeld at the awards shows, and then I actually watched it and realized that it was deserving of those awards. Nothing will ever top Seinfeld, though.
Never seen Cheers, other than maybe two or three episodes. In fact, the Cheers "reunion" style episodes of Frasier were usually ones that I paid barely attention to. There weren't that many of those, though. I'm sure Cheers is a fine show. Definitely influential, I know that. I've heard that Wings is a near carbon copy in many ways, and I'm really fond of Wings. Cheers was just a few years before my time.
