Maniac Mansion - Season 1 Episode 5 Fred's A-Courtin'

Fred is spending so much time with his guiney pig Fats that he neglects Casey. Casey finally gets over her inhibitions and tells Fred exactly how she feels about it. Fred is really distraught and goes to his barber for advice. Tony suggests finding the one thing that will make Casey feel special, so Fred buys a home dance kit and sings Casey an ear-splitting rendition of ""When a Man Loves a Woman"". They end the show in each other's arms.
