In reply to The Lemming:
I remember my parents liking them and as a kid I had to watch what they watched (one telly, 4 channels, no ipod, internet or computer). I think my parent's generation (Veterans) liked bland, not too offensive, comedy and these guys were good at that.
I think there are still a lot of my parents generation (my parents included) still alive and they are the ones most likely to still be watching mainstream TV.
