The Nanny - Season 5 Episode 11 Rash to Judgment

Val has two tickets for Michael Bolton's album premiere party, so Fran asks Mr. Sheffield on a romantic date. She's terrified with a weird rash that appeared all over her body, and rushes to the hospital after Mr. Sheffield decides to take her up to a room for their first intimate night together. She gets a cortisone shot from an inexperienced doctor, which makes Fran swells like a balloon. The romantic night is ruined, thanks to Sylvia's squash-filled pasta that gave Fran the allergic reaction.
