I must admit in my many years of watching (and re-watching) "G.I. Joe: A Real American Hero," I never asked the obvious question Gizmodo posed: "If knowing is half the battle, what's the other half?"

While most people probably assumed the other half was "doing," Nerduo's "The Battle" tee drops some science on the squares:

Red lasers and blue lasers add up for a full 100 percent of the battle. That's math.

Now you know, etc. Let's just hope the folks behind "G.I. Joe: The Rise of Cobra" are wise to this recipe, or at least a variation of it.
