Follow in my footsteps...

On the way to preschool, a doctor had left his stethoscope on the car seat, and his little girl picked it up and began playing with it.

"Be still, my heart," thought the doctor. "My daughter wants to follow in my footsteps!"

Then the child spoke into the instrument, "Welcome to McDonald's. May I take your order?"

U.S. daylight saving time

In 1918, the U.S. first began daylight saving time (DST) on Easter Sunday, when clocks were set ahead by one hour. The idea was sponsored by the Daylight Savings Association. N.Y. Senator William M. Calder introduced the bill to Congress on 17 Apr 1917. It was initially defeated, but subsequently passed by roll-call on 27 Jun 1917. In recent years in the U.S., up to 2006, clocks were changed at 2 a.m. on the first Sunday in April, and reverted on the last Sunday of October. Effective in 2007, DST is set by Congress to begin on the second Sunday of March and end the first Sunday of November. The concept had already been introduced in Great Britain as a fuel-saving measure during wartime, in order to conserve coal stocks during WW I.* [Image: Poster displayed in New Haven Railroad stations, 1941]
