On "Stump the Panel" the panelists are supposed to come up with mundane and science-fictional uses for objects supplied by the audience. Indeed, in Rhonda Eudaly's, S. Andrew Swann's, and Lou Antonelli's imagination things like a pen, a nail file, and a box of Tictacs become something completely different. Especially the nail file. Rhonda had to restrain her imagination regarding this object, because there were children in the audience. :-)
Here is an article about an older "Stump the Panel" at the ArmadilloCon 2006, featuring James P. Hogan's inimitable wit.
