OK young punks-
we still got 2 eyeballs and if it wasnt for us old guys yall probably wouldnt know your ass from a hole in the ground from a pointer to an argon-ion.
So.. Watch those beams
Catch them strays
And mostly importantly...
goggles if you dont know what ur doin
Like Sam Sez:
"What? Youre only equipped with one set of eyeballs?"
