Who is the real father of that kid?

[itsmelisa]

One night, a father overheard his son saying his prayers, "God bless Mommy, Daddy, and Grammy. Goodbye Grampa."
The father thought this was strange, but soon forgot about it. The next day, the Grandfather died.

About a month or so later, the father again heard his son's prayers, "God bless Mommy and Daddy. Goodbye Grammy."
The next day, the Grandmother died. The father began to worry about the situation.

Two weeks later, the father again heard his son praying, "God bless Mommy. Goodbye Daddy."
This alone nearly gave the Father a heart attack.

The next morning, without saying anything, he got up early and went to work. He stayed in his office all day.

Finally, after midnight, he went home. He was still alive! He crawled into bed with his wife and apologized.
"I'm sorry honey, I had a really bad day."

"You had a bad day?" his wife yelled. "The mailman dropped dead on the porch this morning!"
