Jennifer is woman who appeared in the commercial of Sneakers.
When Homer gains weight after starting a new diet, Marge wondered whether Homer was cheating on the diet. Then she saw a Sneakers ad on TV. There was a woman called Jennifer who was afraid that her acupuncturist boyfriend sticked it in someone else.

She then asked TV for help.
