Save the Last Dance for Me (S01E07)

The students persuade Miss Bliss to approach Mr. Belding about relaxing the rules to host an 8th-grade dance. Mr. Belding hesitates but ultimately agrees, provided that Miss Bliss oversees the event. She initially declines because she has prior plans for the night. However, since Mr. Belding insists the dance won't happen without her supervision, she reluctantly agrees to chaperone. When she attempts to cancel her date, Mr. Belding mistakenly thinks she wants him to accompany her, so she ends up taking him along to the dance.
