12 Completely Insane Inventions That Actually Got Made

12. Thumb Sucking Inhibitor

Thumb sucking is no joke, it can ruin your teeth, damage your thumbs and open you up to the ridicule of your peers.

If you want to kick your thumb sucking habit to the curb, then boy do we have the device for you. 

This Thumb Sucking Inhibitor consists of a barbed steel girder that slips inconspicuously over the thumb and prevents the wearer from putting their thumb anywhere near their mouth ... or anywhere else for that matter 

(On that note, users should exercise extreme caution if wearing the device whilst using the lavatory - one lapse in concentration could end in disaster).

Now, you no longer have to worry about the social stigma of thumb sucking, as everyone will be too busy laughing at your thumb-mounted chastity belt to care whether or not you indulge in the occasional thumb suck.
