Nile is tired of losing the squash tournament in his and Frasier's division, so he dumps Frasier to play with someone else, leaving Frasier partner less. So Frasier ends up partnering with an attractive woman named Chelsea who happens to be a P.E. teacher, and after their victory they begin dating.
Though things take a weird turn after Frasier witnesses Chelsea push a student too hard, and it brings up memories of gym from his high school, and from that moment he can’t look at her without seeing his old gym teacher.
The whole time Frasier is with Chelsea when he can't look at her without seeing his old gym teacher was hilarious, the looks on Frasier's face when they where together was great, and after Frasier confesses that he wasn't good in gym Chelsea starts to see the girl that she pushed to hard, because she wasn't very good in gym either.
