E=mc^2 Is Incomplete

I wonder if people who do not study physics actually realize that the actual equation has another term in it?

I lost count how many times someone has told me that since E=mc^2, and photon has energy, then it MUST have mass!

These Minute Physics videos are pretty good Zapper, but I don't like this one because it doesn't get across the way the momentum term flipflops into the mass term in pair production, then back again in annihilation.
