Corrected entry: Sheldon claims the X-Men were named so after the X in Charles Xavier's' name. In The X-Men #1 (1963), Professor X states that mutants possess an extra power that humans do not have. Xavier then says "That is why I call my students... X-Men, for EX-tra power!"
Corrected entry: Sheldon refers to the "Hillbilly Peace Prize" in connection with Penny. Sheldon would have corrected anyone else who said such a thing. He would point out that that word "hillbilly" refers to people who dwell in rural, mountainous areas in the US primarily in Appalachia, the Ozarks, and other less well-known mountain chains. Nebraska, where Penny is from, is rural, but being a Great Plains state, has no connection at all to the term, not to mention a lack of mountains.MFWills
