In high school, I once got to tour the zoo with zookeepers guiding and taking us back in the more private spaces.

(Standing 2 feet away from a 500 pound still-growing tiger is a memorable experience. Especially when the keeper reaches through the grate to pinch the sleeping fella’s toe bean.)

One of the exhibits we got more in depth was this endangered wild horse, where they were part of a breeding program.

The zookeeper was laughing his ass off as a dad was trying to explain what the horse was doing (rocking back and forth…) to his kids.

When the family left, the zookeeper turned to us, and apologized and said “the stallion is masturbating.”
