The opening ceremonies of the London Olympics are probably going on already, but we in the U.S. will have to wait until prime time to see them on TV. To hold you over until then, here's a compilation of the lighting of the Olympic cauldron from previous Olympic opening ceremonies, from 1968 to 2010. Some are just lighting a cauldron, but if you recall, there were some awesome stunts, like the time they shot an arrow to light the cauldron, the time the Olympic Flame entered the stadium by ski-jump, and the one where the cauldron was lit by an athlete standing right there inside it. Don't remember? Then you can see it here.
