Half A Car
As we have discovered, some blockages are quite simply bigger than others in streams and gutters. Back in 2014, a cleaning service with a specialty in drain unblocking were stunned by a blockage caused by a discarded mini automobile. This was one of the biggest objects found in London. An amazing result nonetheless, the drainage task for that year cost a whopping £70 million. The parker of said car must have a couple of regrets..

Random Jaw Bones
For obvious reasons, many objects that are found in the sewers will not give off an indication of their origin. Such as the case of a Canadian drain back in 2009. A strange jaw bone was discovered, and it is not quite confirmed where it came from. It was thought that the bone may have come originally from a variety of herbivorous species. Not unbeknownst to Canada, bone discovering is a more common occurrence, due to the mass of dinosaur remains found in the land. A bone being found in a finished cave however, is somewhat rarer.
