Interesting to hear. I watched Cheers, almost religiously (a time ago, I suppose), and I could just never get into Frasier. I'm not sure I've ever laughed as hard as I did when watching Cheers; it unfortunately doesn't hold up all that well, but I still hold it dear nonetheless.
It's been a while, but maybe I'll give Frasier another shot, even if only as some quasi-filler. :)
