Having portrayed the Dentist in Little Shop of Horrors myself, I can assure you that the headset you see here, a kid-friendly nitrous oxide delivery helmet paired with a Game Boy, is absolutely not an instrument of torture...
...That model comes in teal.
And as a guy who had multiple major surgeries as a kid, I can say that I'd rather get hooked up to Boston-based anesthesiologist Geoffrey A. Hart's "PediSedate" than the vituperous ethers they used when I was a wee one. Hart claims it's been "very well received by parents, kids and health-care workers." And nitrous-heads, too, I bet!
It works like this: first you convince your child that he or she isn't being strapped into a Saw-style device meant to rip the mandible from the skull. Then you turn on the N02 flow, hook up a videogame, and watch your tot buttonmash his- or herself into a very light coma.
What's not to love? Aside from the sex offender name and the concept of a helmet that gasses children in an entertaining way... Do they come in Irresponsible Adult sizes? And can I get mine in teal?
