A Brazilian man, Joao Leite Dos Santos thought it might be fun to play with the monkeys at the Sorocaba Zoo near Sao Paulo.

Dos Santos, not expecting aggressive behavior from the animals, hopped a short fence in order to get closer, while many bystanders stood back laughing or videotaping the incident.

According to the Associated Press, he was drunk at the time he approached the spider monkeys. In the graphic video, which you can see for yourself below, it’s apparent that the encounter didn’t end well for the mechanic. The monkeys quickly assessed him as a threat, and easily bit him on the arm and hand, causing severe bleeding.

Can't blame the monkeys here!

Here's a hint: When you go to the zoo, stay out of facilities designed specifically for the animals!
