One day, some primitive guys were watching their wives drag
a dead mastodon to the food & fire area. It was exhausting
work; the guys were getting tired just watching.
Then they noticed some large, smooth, rounded boulders and
they had a great idea! They could sit on top of the boulders
and get a better view of their wives working.
This was the first in a series of breakthroughs that ultimately
led to television...and later to the remote control.
