Found a four pack of these toys at a store so I had to get them. It’s pretty amusing how something so simple and wind up can be entertaining for multiple moments at a time, because it can serve so many purposes while retaining comedic timing. Is it cold outside? Wind them up. Someone tried to be funny? Give them a round of applause. Just want to make some noise? Chatter away. A person won’t shut the fuck up? Imitate them with the toy. Possibilities are only limited by your imagination. As far as the toy goes, I will say that depending on how you hold it, the chattering velocity will vary. I find that holding from the bottom mandible allows both mandibles to move, as opposed to just the top moving if you were to plop it down on a flat surface such as a table. It also doesn’t really last too long unless you want to fuck up the winding mechanism, so it’s best enjoyed in short bursts.
