Disclaimer: This is the God's honest truth because I know 2 people that witnessed it.
Man in his 50s or 60s had cancer and passed away in July. He had 2 close friends and they always played jokes on each other. They were 2 of his pallbearers and were strategically placed at his feet one on either side. The hearse parked as far away from the graveside as possible so they were forced to carry the casket a long way in the July heat at 3:00 in the afternoon. They noticed how these 2 guys were struggling something awful and were sweating like crazy. They finally got the casket to the graveside and everyone got seated. The preacher starting talking about the 2 close friends and how they played jokes on each other, while this was going on the funeral director opened the casket and pulled out 2 huge cement blocks from the feet area. On each block the man had written "Ha ha I got the last laugh!" and had signed his name to them and they were presented to his 2 friends!
