From my email, thanks, Stan:
An elderly man suffered a massive heart attack. The family drove wildly to get him to the emergency room.
After what seemed like a very long wait, the ER doctor appeared wearing his scrubs and a long face.
Sadly, he said, "I'm afraid Grandpa is brain-dead, but his heart is still beating."
"Oh, Dear God," cried his wife, her hands clasped against her cheeks with shock. "We've never had a Democrat in the family before!"
