If we jumped into our pants simultaneously placing both legs in at one time, we would land heavily on the ground. As a majority of us are getting dressed at the same time of the morning, the cumulative effect would cause an earth tremor. Due to the use of time zones, the tremor established In Eastern Time would arrive in the central zone at precisely the moment all those people were jumping into their pants. The tremor would increase in size exponentially, and proceed west to combine with the mountain zone folks as they get dressed. As this cycle encircles the globe, it would feed upon the next day’s tremor and eventually cause the earth’s crust to break apart and float into space.
And this is why we put our pants on one leg at a time.
Gosh, I’m glad someone did the maths.
