I remember when we had our little conference classroom thing set up in our school. A buddy of mine was supposed to take a glass, and he put on his aunt's (I think) huge bifocals with the thick frames and lenses. Then he threw in a huge lip of skoal and sat down and tried to read what was on the screen. We couldn't understand what they were saying because they had thick French accents and the audio feed was terrible. Every now and then we'd throw a shoe, or a person, across the screen. People were confused but it was a pretty good day.
