Taxi - Season 4 Episode 10
Louie Goes Too Far

When Louie spies on Elaine changing in the garage bathroom, she enlists a NOW representatives help and gets Louie fired. Louie appeals to Elaine at her apartment one evening though and begs her forgiveness (and her help getting his job back). After Louie exhibits actual remorse and demonstrates through a touching story that he knows how it feels to be violated, Elaine accepts his apology (and presumably gets him rehired at the garage).
