Frasier was brilliant.
Actually, Channel Four shows (or used to, it's been a while since I was home in the morning) some quite good US sitcoms.
Everybody Loves Raymond (I didn't, I hated him, but loved his brother, Robert!!).
King of Queens, is quite amusing too.
Some are born great, some achieve greatness and some have greatness thrust upon them.
The rest of us are a bit crap.
