The Simpsons S18 E03 Please Homer, Don't Hammer 'Em

"Just a product of society that's lost its good manners."

Marge reads Homer's carpentry books and becomes very handy at fixing things. Gender bias keeps the townspeople from accepting a female carpenter, so Marge pretends that Homer does the work. Meanwhile, Bart torments Skinner when he learns the principal has an extreme allergy to peanuts.
