Two friends, Bill and Bob, were out fishing one day when Bill suddenly clutched his chest and fell over. Panicked, Bob called 911 and the operator told him to do CPR immediately.
Bob frantically tried to remember his CPR training as he started chest compressions, but he couldn't quite recall how many compressions to give. So in his panic, he started counting out loud, "1, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King."
The operator on the other end of the line was shocked and confused. "Sir, what are you doing? That's not how you do CPR!"
Bob replied, "I know, but last time I did CPR, I gave him a joker and he woke up laughing!"
