The Simpsons - 10 Classic Easter Eggs You Probably Missed In Season 17

2. Lisa's Wig Is Homer's Hair - Girls Just Want to Have Sums

The relationship between Homer and Lisa is one of the most interesting dynamics in the show, offering up something rather unique in the pantheon of sitcom families. The question of respect and appreciation has come up several times throughout the series, creating some of The Simpsons most emotional beats. Season 17 offers up a more subtle wink to this in Girls Just Want to Have Sums, where Lisa pretends to be a boy in a gender-segregated Elementary School so she can learn maths. Back before tearing it out over Marge's pregnancy/succumbing to male pattern baldness/suffering from years in a nuclear power plant, Homer sported a luscious head of brown hair, to which Lisa's wig for Jake Boyman bears more than a passing resemblance.
