Not sure if I understand your post. Are you suggesting that a funeral is a good time to shake yourself free from the boring and tiresome routine of everyday life? To make waves? I think it's OK to leave funerals to the grieving and the heartbroken and save the fun for the Ren Faire.
I recollect a couple of funerals in the last 20 year which were totally dour. But most funerals I've attended have had either the priest, minister, celebrant, of persons delivering the eulogy saying things that made the people present laugh fondly at aspects or events in the deceased's life. Does this not occur where you live?
