While meeting with Mr. Weed and Miss Ironbox in Mr. Weed's office you see a calendar in the background. The calendar has the months abbreviated by a letter. The months March and May are abbreviated with a "w" while they should be abbreviated with an "m"
When Peter Griffin goes into Mr Weed's office there is a Productivity Calendar behind the desk. It changes name during shots, 'Produtivity Chart' and 'Productivity Cha'.
Lois seems to think Peter is idiotic when he tries to give himself a breast exam after he discovers his feminine side. However, it really is possible for men to get breast cancer.
