The so-called "fatberg" that you see at the end (a term actually being used by the Thames Water utility company) weighs in at an estimated 15 tonnes, or slightly more than 16.5 American tons, and was found late last month by utility workers in the sewers of the London suburb of Kingston after residents reported no longer being able to flush their toilets. "Given we've got the biggest sewers and this is the biggest fatberg we've encountered, we reckon it has to be the biggest such berg in British history," said Gordon Hailwood, waste contracts supervisor for Thames Water, in what is by far my favorite statement I can ever remember discovering on the website of a water utility.

Wow. That is truly disgusting.

don't put oils down the sink, folks.... also.... I don't think i've been so disturbed by a news story before... I once had to walk past a grease bucket of a Wendy's walking in the door to work many moons ago.... the stank still haunts me.. I don't even want to imagine the smell.

Oh THANK YOU - I hadn't considered the smell until you mentioned it.  

You definitely don't want to watch the video .... not even the part where the camera briefly retreats and then goes ramming speed at the fatberg.
