What about this one!
At the funeral, each man put an envelope in the coffin. Riding away in a limousine, the priest suddenly broke into tears and confessed, "I only put $20,000 into the envelope because I needed $10,000 to repair the roof of the church."
"Well, since we're confiding in each other," said the doctor, "I only put $10,000 in the envelope because we needed a new X-ray machine for the pediatrics ward at the hospital which cost $20,000."
The lawyer was aghast. "I'm ashamed of both of you," he exclaimed. "I want it known that when I put my envelope in that coffin, I enclosed a check for the full $30,000."
