Are you a curmudgeon? Do you identify with Statler and Waldorf, the irascible and jeering characters who heckled from the balcony on The Muppet Show (1976 to 1981) and other Muppet productions? Would you like to put them on a shelf so they can talk smack about your life choices?

It’s all possible thanks to Prop Store. The entertainment memorabilia auction house has announced it will be putting the disembodied heads of the popular cranks up for bid, with an estimated price of $40,000 to $60,000 expected.

The heads measure 13.5 inches by 10 inches by 15 inches and appear to be in immaculate condition, with their foam intact and their flecked surface free of wear. A puppeteer’s sleeve is attached to each one. Waldorf sports a tag that includes the name of Muppets creator Jim Henson, which could indicate it was used by Henson himself at some point. Naturally, the inseparable pair come as a set.

The dismissive duo was first seen in the original 1975 pilot for The Muppet Show. Each is named after a New York City hotel—the Statler Hotel and the Waldorf-Astoria. (Waldorf’s wife is named Astoria.) Waldorf, incidentally, is the one with the mustache.

Other items up for sale include a prototype Coraline Jones puppet from 2009’s Coraline signed by Neil Gaiman, which could fetch between $10,000 and $15,000; a Terror Dog stop-motion puppet from 1984’s Ghostbusters ($6000 to $8000); and a Gremlin puppet from 1990’s Gremlins 2: The New Batch ($5000 to $7000).

The auction will run from June 29 through July 1. You can visit the Prop Store website to register to bid.
