London's latest fatberg - a congealed, rock-hard mass of fat, grease, wet wipes, used diapers, condoms and more - clocks in at 130 tons, and it's more than 800 feet long, according to the BBC.

Blockages caused by wet wipes and cooking fat occur at a rate of roughly eight a week, and Thames Water says it spends about 1 million pounds, or just over $1.3 million, a month removing them.
Thames Water said work will continue throughout September until the sewer is clear.
A enormous "fatberg" - the weight of 11 double-decker buses - has been discovered in an East London sewer.
Work in Whitechapel Road to remove the huge fatberg has now started, with crews using high-powered jet hoses to break up the mass before suction tankers draw it out.
A fatberg weighing the same as 11 double decker buses and stretching the length of two football pitches is blocking a section of London's ageing sewage network.
"When it comes to preventing fatbergs, everyone has a role to play", said Rimmer, in the company's statement. "It's frustrating as these situations are totally avoidable and caused by fat, oil and grease being washed down sinks and wipes flushed down the loo", he added. "It's fortunate in this case that we have only had to close off a few parking bays to get to the sewer".
CCTV camera inspections revealed the 1200mm-high by 700mm-wide sewer was totally blocked by the fatberg, which is 3.5 meters below ground. "Often we have to shut roads entirely, which can cause widespread disruption, especially in London". "The sewers are not an abyss for household rubbish" Rimmer said.
