I guess they should have re-hearsed that a little more
and FWIW it's not sadly funny it's hysterically funny.
Years ago a fellow from my congregation died - as the hearse pulled out it rearended the car ahead of it - he was a joker in life and would have loved it.
Then his widow decides she wants to spread his ashes - initially in the backyard. After I convince her that this is a bad idea (If she ever moved and yet wanted to show grandkids where grandpa was buried she would have to park across the street) So she decides instead to spread the ashes in a park with a gorgeous overview - which is illegal as it isn't a properly registered burial ground. She goes at night to spread the ashes, has them in a bag, cuts the corner and starts walking briskly.
She then goes home and tells her grown sons what she has done.
After work the next day the sons go to see the place, they're standing looking at the view when one brother taps the other and points down. Mother has cut too big a hole in the bag so all the ashes are in one big pile at their feet.
Other brother casually swings his foot to scatter them somewhat only to find that they are frozen solid, story finishes with both of them on their knees with ice scrapers chipping away at dads ashes to spread them. They said they were laughing so hard tears were streaming down their faces. He (the father would have loved it) and needless to say we never told the mother.
