It doesn’t exactly have the “ooh” factor of a Lucille Ball caricature hanging on Sardi’s wall. It does, however, inch toward the “eww” factor of, say, a faded 34C underwire tacked up on the ceiling of a dive bar. What is it? Just a wee crumb of a toastie eaten by the Libertines co-frontman Pete Doherty.

That’s right. There’s a museum where you can view the dried-out crust of a British pop star’s cheese, tomato and pesto panini that he ate at a cafe in a Cornish seaside village. Owners Michael and Francesca Bennett wanted to commemorate the visit of celebrities to their seafront cafe, the Old Boatstore. When photographer David Bailey visited, the couple told the BBC, they were so excited they decided to keep a bit of the sandwich he’d consumed. The Museum of Celebrity Leftovers grew from there.

Now, when you visit Kingsand in the U.K., you can view about 20 “artifacts” sealed under tiny glass domes and kept on a bright blue shelf hanging on the cafe wall — the museum’s entire collection. Ogle actress Mia Wasikowska’s wedge of zucchini. Examine the end of comedian Hugh Dennis’ ice cream cone. Ruminate over retired BBC weatherman Craig Rich’s pasty crust.

No preservatives have been added to the remains, and Michael Bennett assured the BBC that none of the exhibits seem to be getting moldy, just dried and shriveled.

The Bennetts have owned the cafe for nine years and serve mainly vegetarian fare with locally sourced seafood when available. So don’t expect to see a bite of Prince Harry’s burger anytime soon. However, Charles and Camilla have paid a visit. The Museum of Celebrity Leftovers has a tiny silver crown adorning the glass dome protecting Charles’ relic: a teensy crust of bread pudding.

It’s unlikely that the Prince of Wales and Duchess of Cornwall came just to see the odd exhibit, as the display of food waste is more kitschy than captivating. It may, however, have some competition for the world’s most underwhelming excuse for a museum. Consider the Asphalt Museum with its chunks of tar at Sacramento State College in California. Or the Barbed Wire Museum in LaCrosse, Kansas. And you might just get “sucked in” — their pun — at the Vacuum Museum along Route 66 in Missouri. (For more, see our list of the world’s weirdest museums.)

No reason to cross the Hermitage or Smithsonian off your must-see list just yet. En route between the two, you might want to stop in the Old Boatstore for a bite to eat. Who knows who may be seated next to you.

What’s the stupidest museum you’ve ever visited?
