The Simpsons has become such a cultural institution that there's very little in the series that hasn't been mined, examined or made real.
Even the most throwaway gags are now a reality, such as this moment from the fifth season episode, Homer's Barbershop Quartet. Take a look.
Well, as you can probably guess, the reference to Yoko Ono's bizarre performance art is actually now a cocktail that you can pick up in the Candelight Bar in Dundrum Town Centre - and here's what it looks like.

All served in a hat.
