Q: Why must we put on our pants one leg at a time?

Ans: 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. This is why we put our pants on one leg at a
time.
