It’s a bird. It’s a plane. No! It’s … FATBERG! Cleanup crews in London had their work cut out for them recently when a 15-ton “fatberg” – a bus-sized wad of lard and wet wipes – was discovered blocking sewage in the southwest part of the city.

Utility company Thames Water said the mound of "wrongly flushed festering food fat mixed with wet wipes" was discovered under a road in the London suburb of Kingston.

Using high-pressure water jets, workers spent 10 days dislodging the fatberg, which is estimated to be the biggest "berg" in British history. Authorities claim repairing sewer lines will take weeks and advise residents to not pour fat down the drain or to not flush sanitary napkins down the loo.
