Story
Peter uses the transgender toilet at a baseball game and is taken for transgender himself. He goes along with the mistake and starts dressing as a woman, since Bert and Sheila support the transgender community and the benefits at work follow. Matters harden after an accident at a low ceiling fan club puts him in a coma, during which his two bosses arrange gender reassignment surgery for him. Life as a woman does not suit Peter, and Ida Davis is the one who gets him out of it.
