Sitcom from 1970s

I am searching for a TV show that was adorable and hilarious in the 70s. It was aired after Monty Python's Flying Circus show. It was about a newlywed couple. She was funny and always into something. The English Lucy! He was tall, she was short w/dark hair and dimples. I cannot remember either of the actors names. Any help will be appreciated! Thank you. :)

Could it be No Honestly?
