I like the "only four tickets can still win, but you have to show initiative and call Sgt. Slaughter on the phone" feature to the contest. It teaches kids how to have character, while at the same time emptying out the warehouse filled with those things as fast as possible.
I sent away for the Sgt. Slaughter figure but never got it. It's something my mother likes to remind me every time my childhood, Sgt. Slaughter, or G.I. Joe happens to pop up in conversation. Which isn't often but she does manage to remember at every opportunity.
