Yeah...I got it for almost nuthin' 'cause it was just layin' out where any little kid could get it & bust it, & I told the woman running the store that it was extremely dangerous to do that, & she was opening herself up for a big lawsuit, potentially. OK, so maybe that was an exaggeration, but back when I was a Snarky Little Boy, I developed a "Radar" for finding stuff like this & foolin' w/it...Never broke anything, but I was just VERY dam luicky, too..And I'm sure there are OTHER Snarky Little Boys out there...
