Save the Last Dance for Me - S1.E7

The kids convince Miss Bliss to ask Mr. Belding to bend the school rules and allow them to have an 8th grade dance. Mr. Belding reluctantly agrees if Miss Bliss will chaperone the dance. She says she can't as she already had a date for the evening. Mr. Belding won't allow the dance unless she agrees to chaperone so she finally says she will. When she tries to break her date, he assumes she wants him to come with her, so she ends up bringing him to the dance with her.
