In the middle of the night, I think it might be at 1, 2 and 3AM local time here, MeTV has a Rats dream lineup. They show Mannix, then Cannon, then Barnaby Jones. I love all those shows as well and occasionally when I am between contract assignments I will watch one of them, or maybe 1 and a half. Can’t make it through 3 in row at that hour though.
