Never mind the automobile, the polio vaccine, the computer, the smart phone.
I picked one of these up at a dollar store recently.
The ultimate in self-pleasuring tools, and for only $1.06.
Years from now, when archaeologists dig up a cell phone or a computer, they’ll know exactly what they are. But the scalp massager – that’ll have them scratching their heads.
But seriously, CoastalMaineiac, I think that thing is actually an alien brain control device.
You know, it does sort of have a hypnotic effect to it.
Alien device??? Hell, that thing is the alien.
… they have sex by wrapping their legs around their mates heads and bumping uglies.
Well played. 
It’s a close second after the TV remote.
Oh! We used to have one of those. I think someone got it as a gag gift.
The sensation of a dozen, wiry, alien fingers slithering down your scalp is actually slightly more pleasant than it sounds.
Slightly.
This is the best $1.00 I ever spent at the dollar store.
Ladies, don’t even consider using that on your boobs. It’s not only agains the law in 37 states (including yours!) but it’s also just a really bad idea. Don’t do that. Ever. Are you listening?
Sounds like there’s a story here…
