When Homer somehow obtains two tickets to a candy convention (think tearing through chocolate bars in search of them) he steals the rarest gummy of all, "The Gummy Venus Di Milo." After Homer escapes escapes, he stresses when he gets home that he can't find his "precious Venus." It eventually turns up on the babysitter's butt who looked after Bart and Lisa while Homer and Marge were out. Homer, being the drooling, hungry oaf he is swipes the gummy off her which leaves her thinking he sexually harassed her.
What ensues is a media storm of homer-bashing, deception and a Denis Franz portrayal as Homer in "portrait of an assgraber." In the end though, Homer gets lucky with the help of a certain Scotsman.
This is a Simpsons classic, the jokes are plentiful and the animation is great.
