He looks great in a fedora - we'll give him that. But surviving a tumble over three 100-foot waterfalls or toughing out an atomic blast by climbing into a refrigerator? We love Indy, but his exploits seem to be over the top when it comes to elementary physics. From hovercrafts to the quartz crania of aliens; find out what scientific concepts in the latest bullwhip adventure are more than a little nutty. Plus, the real crystal skulls, and the man who discovered that two of the most famous are fakes. Also, an incentive to tackle that to-do list: the 2012 Mayan apocalypse. And, If I were Indy, our Hollywood Skeptic puts himself in the hero's boots. It's Skeptical Sunday, but don't take our word for it.
