Tactical flashlight which can blind you permanently....
(sold on Amazon.ca -- curious if also available in the US)
My new tactical flashlight works like a dream
Puts out a strong green laser beam
But I should have left it on the shelf
Because I looked at it and blinded myself
Why did I buy that cheap online stuff
My life now is very rough
Cannot see because I zapped my eye
Oh don't buy that crappy stuff, why why why
