Actually, a few days after the wall went up, we have Corporal Conrad Schumann in this famous photograph kind of hopscotching across the rolls of the barbed wire to get across. In 1964, there were, I think, 57 East Berliners that dug a tunnel underneath the wall. And then from that point forward, there were thousands of people that did other kinds of antics like using mattresses, shooting cables with bow and arrow and scurrying across that way, light planes, hot air balloons. They did pretty much anything they could to get out. But eventually the pressure's going to be too much. Why don't we take a look right now at why the Berlin Wall goes back down. So why does the wall go down?
