Raccoons

One time I was at the Audubon Zoo and looking at a raccoon enclosure and out of nowhere this groundskeeper walks up to me and was like "We've got ten times more of the damn things running around the property than in there." He was legitimately pissed. Then he got in his cart and sped away.

I'll never forget how much that man hated raccoons and how mystified he seemed that they warranted a zoo exhibit.
