Time for a true story:
I was in the barber shop one day, and as my hair was being cut my barber was having a very amusing conversation with a gentleman who was something of a local legend. He was a fantastically enthusiastic, comedic, and outgoing personality, and enjoyed some dangerous personal hobbies such as amateur fireworks experimentation and the like. The conversation had turned to end-of-life plans and such, and this gentleman was explaining some insider knowledge about the proceedings of funerals where the deceased is cremated. He explained that a friend from the funeral home had told him that when the urn is present during the memorial service, it is left empty until the proceedings are completed, then the urn has the ashes placed inside and is returned to the family/responsible persons. Since the prior conversation had involved some hilarious ideas about how to sabotage his own memorial service, I saw an opportunity in this revelation. He had shared that he was to be cremated upon his death, so I offered to attend his memorial ceremony with the promise that if he so wished, I would arrange to "accidentally" upend his urn as I passed by, hopefully to the shock & surprise of folks who had no concept it would be empty. This was very much to his liking, he laughed until he cried at the idea, and actually took down my phone number and info. I suppose it wasn't meant to be, because I was never contacted, but I absolutely would've done it, purely out of respect for his wishes and admiration for his outsized personality.
