Ron, A middle aged Republican from Kansas sent me this one.

A kid was sitting on his lawn with a box of newborn puppies when George W. Bush came by on his morning run. Bush asked the boy what the puppies were.
The boy said, "Republicans."
The president beamed, patted the boy on the head and said, "Thatta boy!"
A few weeks later Bush was jogging again, this time with Dick Cheney in tow. Bush stopped at the boy's house, winked at Dick and said, "Hey, kid, what kind of puppies are in the box?"
The boy said, "Democrats."
Bush looked crushed and said, "What happened? A few weeks ago they were Republicans."
"Well," the boy said, "that was before they opened their eyes."
