Ya know, nothing says "a good time" like being able to light a friend's cigarette with a handheld laser. :-)

This is the geeky coolness one comes across when they're looking at portable Night Vision scopes and Infrared Night Vision enhancement lights. Don't ask why I was looking at these... it's even geekier than the lasers.
*wonders how much weight the night vision monocular would add if attached to a Nerf gun*
