Jennifer Love Hewitt is an American actress and singer who appears in the Season Two episode, "Cow Days". She is best known for her role as Sarah in the TV series Party of Five, and for playing Julie James in the movie I Know What You Did Last Summer and its sequel.
At the carnival for the 45th annual Cow Days, there is a booth where players can throw balls into Jennifer Love Hewitt's mouth to win Terrance and Phillip dolls. The problem, and innuendo, is that the balls are bigger than the hole.
While she does not appear as a character on South Park, her likeness is represented by a still photo on a stand.
