I had a ThunderBurp. I also had a Burp gun. Worked like the TommyBurp in the commercial but it was an copy of an M3. Lots of different cap pistols. A luger water pistol that used detachable water filled magazines. Came with two extras.
That's what the antis fear about commerials like that. Those kids having fun with toy guns grew up to become...us.
