"No, I will not accept a microchip."
I was wondering how long it would be until the X-files factor came to play...
Microchips aren't sufficiently small at this point to where they can be inserted with a innoculation needle.
You need something more along the lines of an autopsy fluid-draw needle.
But, just so as you know...
You've already been microchipped, tagged, probed, and released back into the wild.
If you've ever taken an aspirin, cold caplet, or eaten a school lunch, or breathed the air in the DMV, you've been "registered" by your government, which is watching you through a chair-keyboard interface to your computer.
(Sung to the tune of Santa Claus is coming to town...)
They know what you've been reading, they know how much you make, you'd better not lie to them, or you'll disappear post haste...
Oh... You'd better not grouse, you'd better not sigh, you'd better bitch, I'm telling you why, Uncle Sam is spying, on you!
