And as I've said, everyone's entitled to their opinion.
In MY opinion, the phrase "there's a time and a place for everything" exists for a reason.
I happen to think that having someone show up at someone else's funeral and begin an impromptu roast of the deceased is probably just a ta-a-a-ad (I know you like that word) in bad taste.
You may have a differing opinion, which is fine.
Humor is great. Knowing when to use it and when not to is even better.
