Over 20,000 reported cases of crap on the streets of San Francisco wins it a funny smelling crown.

Via KRON4:

San Francisco has been named the 'doo-doo' capital of the United States with 20,899 poop complaints reported in 2017, according to RealtyHop.

RealtyHop did a comparison of 311 poop complaints in Chicago, New York City, and San Francisco.

This study includes dog and human poop sightings.

While 2017 was the worst year on record in San Francisco, research shows that 2018 is on track to beat that.

The 'Doo-Doo Map' from RealtyHop shows the which neighborhoods have the most poop complaints in the city.
