Our physics professor was struggling to draw the class into discussion of Archimede's principle of water displacement. He told us that Archimede noticed that when he got into a pool at the public bathhouse, the water rose spilling over the edge. Excited at his discovery, he ran down the street yelling, "Eureka, eureka!" The instructor asked if anyone knew what that meant.

One student stood up and answered, "I'm naked ! I'm naked!"
