I gotta say Howard and Marina, but I don't know if ya'll consider them a couple. LOL Onslow and Daisy from "Keeping Up Appearances" were funny too. I don't watch a lot of American TV ( I don't really watch a lot of TV at all! ) but I would say Fred and Ethel from "I Love Lucy" were funny. I watch TV with my mom sometimes, but not very often, so these are just the people I see on the shows she watches.
