S2E8 I Am Peter, Hear Me Roar

After being sent to a women’s retreat for making sexist jokes at the office, Peter is initially reluctant to participate. However, after two weeks, he transforms into a more sensitive man. This new version of Peter doesn’t sit well with anyone, especially Lois. During a charity dinner, Lois takes an action that finally jolts Peter back to his old self, ending his brief period of sensitivity.
