Betsy Donovan was Clyde Donovan's mother and Roger Donovan's wife. She was of Dutch ancestry and according to Clyde, she apparently had a very good recipe for lemon bars. She died in "Reverse Cowgirl", after Clyde left the toilet seat up. However, she was later seen alive in the episodes "Jewpacabra" and "You're Not Yelping", which is likely a continuity error.
