Technically I bought 2 of these wild slingshot screaming monkeys for my boys. In reality I bought them for me. The idea is very simple. You slip your fingers into the little folds in the hands and then pull back on the tail and let'em fly across the room as they scream in all their monkey-glory. Every time I let one fly is makes me laugh. The boys also have fun mimicking the monkey scream. Its like my own little primate chorus every time I do it.
So, if you are having a bad day or just need a good chuckle, why not go out and get yourself your own wild screaming monkey. You can tell your friends you really bought it for the kids.
