"This video makes me nervous. The only reason that you can be sure that the monkey doesn't just snap a puppy's neck for the hell of it..."

"... is because it's been widely shared as a 'cute' video. The owner had no way of knowing it wouldn't."

That prompts somebody else share his "monkey story":

When I was vacationing in Thailand about 20 years ago, I was in a busy restaurant that had a small monkey chained to a perch in the corner. I felt sorry for it and went over to give it some attention. I fed it a treat of some sort from my table and allowed it to perch on my shoulder. Then it shoved its fingers into my eye sockets, driving my lids deep into the space between my eyeballs and eyebrows. It wrapped it's legs around my neck and started humping the back of my head, coming before I was able to tear it off.

I came to realize that having a monkey for a pet would be as much fun as taking care of an incontinent, criminally insane person.
