Season 4, Episode 4: Lisa the Beauty Queen
When Lisa has a bout of low self-esteem about her appearance, Homer has the well-intended, albeit misguided idea to make her feel better by entering her in a beauty pageant. At first, Lisa is horrified and convinced that she could never stand a chance of winning. To build up her confidence, Bart decides to become her pageant coach. When trying to show her how to walk in high heels, Bart strikes a pose and it’s pretty clear the animators were using Betty Grable’s very famous pin-up picture as a reference for this scene.
