"My father in law worked for a commercial plumbing company. They got a job putting in all the water related stuff for the primate enclosures at the local zoo. While working near orangutans, they had to not leave their tools unattended, and take inventory when they left. The orangutans would try to use the tools to take their enclosure apart.

Bonus Wholesome: Years later, my son got a book on animals at the book fair. Reading it together, when we got to the part about orangutans it said, "orangutans are so smart, plumbers working on their enclosures at the (Hometown) Zoo had to be careful not to get their tools taken when working on their enclosure."

I said, "Holy cr#p, they are talking about your grandpa!!""
