Insane, Inappropriate, Beautiful, or all three?

If someone told you that when they die they want their body to be cremated, the ashes put into a single firework and set off at midnight over the lake where he/she proposed or first kiss or something similarly memorable… what would you say? This idea came to me a while ago after someone told me about Tibetan sky burials. For both cases I am not sure if it’s just crazy, inappropriate, madly beautiful or a strange combination of the three. What do you think?
