Breakthrough?
Millions of years ago, there was no such thing as the wheel. The only way to move things was by carrying or dragging. One day, some primitive guys were watching their wives drag a dead mastodon to the food preparation area. It was exhausting work. The guys were getting tired just WATCHING.
