Two senior management pals rented a boat and fished in a private secluded lake every day. One day they caught 30 fish. “Mark this spot so that we can come back here again tomorrow,” said one of the management guys to the other.
The next day, on their way to rent the boat, the same guy asked his colleague, “Did you mark that spot?”
His colleague replied, “Yeah, I put a big 'X' on the bottom of the boat.”
The first one said, “You fool! What if we don't get that same boat today!”
