We are the tradguns, my friends

The story:

When we were little, my sister and I loved to perform dramatic reenactments to popular songs of the time. We put on a performance of "We are the Champions" for our parents, who cracked up when our little girl voices sincerely sang out, "Weeeee are the tradguns, my friends". We then pretended to shoot the bejesus out of each other as we sang "and we'll keep on fighting 'til the end". We honestly thought the song was about war and that tradguns were some type of really cool soldier or weapon. We were so surprised to learn the real lyrics from our killjoy father...you mean there's no such thing as a tradgun? Bummer!!!
