After Lisa's new pet guinea pig destroys the Simpsons' living room art, Marge falls in love with a beautiful painting at the Van Houtens' yard sale, which Homer purchases for $20.
Marge removes the frame and finds that the painting bears the signature of Johan Oldenveldt, an artist of some renown.

He added that despite one of a number of criticisms of recent Simpsons being "the cast’s perceived disinterest", in this episode it was clear Smith was giving 100% to Lisa in her obsession over the guinea pigs.
