Half A Car
When it comes to clogs in sewers and drains, some are more serious than others. In 2014, a drain cleaning company discovered half of a discarded Mini car, which was one of the largest items ever discovered in London. While this was an impressive achievement, it turned out that unblocking the capital’s sewers cost £70 million that year. We’re sure whoever parked that car was kicking themselves.

Random Jaw Bones
Understandably, some items discovered in sewers cannot be identified, no matter how much time is spent examining and studying them. In the case of the mysterious jaw bone discovered in a Canadian sewer in 2009, this was the case. The bone could have come from any number of herbivorous creatures. Bone discoveries in Canada aren’t as surprising because the country has a higher-than-average distribution of dinosaur skeletons. Finding a bone in a tunnel that has been completed, on the other hand, is unusual.
