A very long time ago, there was no such thing as the wheel. 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.
