A father put his three year ol...
A father put his three year old daughter to bed, told her a story and listened to her prayers which she ended by saying, "God bless Mommy, God bless daddy, God bless grandma and good-bye grandpa."
The father asked, "Why did you say good-bye grandpa?"
The little girl said, "I don't know daddy, it just seemed like the thing to do."
The next day grandpa died.
The father thought it was a strange coincidence.
A few months later the father put the girl to bed and listened to her prayers, which went like this: "God bless Mommy, God Bless daddy, and good-bye grandma."
The next day the grandmother died.
"Oh, my gosh", thought the father, "this kid is in contact with the other side."
Several weeks later when the girl was going to bed the dad heard her say: "God bless Mommy and good-bye daddy."
He practically went into shock. He couldn't sleep all night and got up at the crack of dawn to go to his office. He was nervous as a cat all day, had lunch sent in and watched the clock.
He figured if he could get by until midnight he would be okay. He felt safe in the office, so instead of going home at the end of the day he stayed there, drinking coffee, looking at his watch and jumping at every sound. Finally midnight arrived, he breathed a sigh of relief and went home.
When he got home his wife said "I've never seen you work so late, what's the matter?"
He said, "I don't want to talk about it, I've just spent the worst day of my life."
She said, "You think you had a bad day, you'll never believe what happened to me. This morning the milkman dropped dead on our porch."

Snow-melting apparatusIn 1946, the first test in the U.S. of a snow-melting apparatus embedded in a sidewalk was made in New York City. The department store, Best & Co. installed 15 coils made up from 4,530 feet of pipe. A mixture of about 67% water with 33% Zerex was circulated, effective to prevent freezing to as low as -5 deg.F. It was first put to use shortly thereafter, on 26 Dec 1946, during a blizzard. This was not the first method to melt snow devised in the U.S. On 27 May 1890, black American inventor F.J. Farrell was issued a patent for an "Apparatus for melting snow" (No. 428,670), which was a cast-iron box laid beneath the street gutter and heated with steam. |
