One time my dad took my brother's walkie talkie and had us and about 10 kids in the neighborhood convinced that we had picked up a signal from a plane that was crashing towards the Earth. We were running up and down the streets for an hour with our eyes on the sky listening as the "pilot" tried to reach someone for help. Dad's windows were open so we eventually caught on to the heinous laughter echoing between the houses after every mayday.
