When I was a kid I had a squirt-gun version of the lasergun from the show.
I can't recall much about it other than it was like brass-knuckles in shape and shot something like 6 to 9 streams of water at the same time.
I remember it was kind of cool.
But then again, I did eat a lot of paint chips as a child.
(Well, not really but I need some sort of excuse for my current behavior!
)
