I thought the "friends" and "seinfield" thing was because the shows ran on Thursdays (meeting nights)
My father and sister enjoyed watching Seinfield and my mother did when she "got" it. I don't think they have ever really seen Friends unless ins the reruns in the afternoon that Im watching which doesn't seem to really bother them. Then again my mother has sat and watched Will and Grace with me which I was shocked about.
(Of coarse my father was always more leniate with TV shows because he liked to watch them too....it was only extreme sexual or spiritistic things that got switched off but violence was usually fine even when I was little)
BTW-----I loved the list...made me laugh and I think I might just pass a copy out to my friends etc.
