I remember on several occasions the student section was used as a flash card section
there would be several different colored cards and a card with listed colors on it numbered
there would be a leader who would yell what number we were supposed to do
on his command we were supposed to hold up the appropriate color
this was only done when we were on national tv with the blimp circling around
course there was always the guy who would purposely hold up the wrong color or the guy who would try and break the record for the card fling
those were the days
