Yoko Ono 's new art exhibition features a physical reference to a gag from a 1993 episode of The Simpsons.

The joke in question takes place in a season five episode, "Homer's Barbershop Quartet", which follows Homer, Barney, Apu, and Principal Skinner as they form a band named the Be Sharps - the episode loosely parodies The Beatles' rise and fall (George Harrison even makes a guest appearance). At one point, Barney visits the local bar with his new partner - "a Japanese conceptual artist" - who orders "a single plum, floating in perfume, served in a man’s hat."

Ono has curated the exhibition, which takes place at the Reykjavík Art Museum and features a piece by Icelandic performance artist Ragnar Kjartansson. That piece is A Single Plum, Floating In Perfume, Served In A Man's Hat.

Ono’s exhibition, YOKO ONO: ONE MORE STORY..., runs until 5 February 2017.

Remember The Simpsons when @YokoOno asked for "a single plum, floating in perfume"?
