Brass Monkey On My Back

Yesterday I went to the cemetery, visiting my grandparents before the Father's Day etc. Afterwards I wandered around a bit, looking at the gravestones, and came across one with this:



My first reaction: haha, that's clever!
Upon some reflection: Do I want to use my gravestone for inside jokes? Do I want people to say "haha that's clever" when they look on my grave?
I am not entirely sure... But I still think it is quite clever indeed.
