1x16 - Maniac Mansion

Idella tells Harry that she misses their old relationship. He is distressed and asks Fred to turn him into a giant fly to save his marriage. Idella is delighted, but every time someone comes over to the mansion Harry has to hide since he still has giant wings. He's sick of all this hiding, and confesses how he feels. Idella finally accepts that Harry was happier as a fly, and they decide that Harry will be shrunk back. The show ends with Idella deciding to share the cooking for the family.
