Here’s a real “ay carumba!” moment.

Above is the cast – in costume – of “Mr. Burns: A Post-Electric Play,” Anne Washburn’s musical being staged in NYC.

The premise of the show: After the apocalypse and the end of the world, a group of survivors entertain themselves – and survive – by re-enacting old episodes of “The Simpsons.”

The group starts out by trying to remember lines, particularly from the classic “Cape Feare” episode featuring Bart and his family menaced by Sideshow Bob.

Eventually the effort turns into actual stage productions featuring those masks.

The same masks I’m afraid I’m going to be seeing in my nightmares tonight.

Yikes.

Thanks to Cartoon Brew for calling our attention to the production.
