I can't decide if this is cruel or clever

I'd love to leave instructions in my will to the effect of ensuring a closed-casket viewing-funeral session. At the height of the gathering, the will arranges for some kind of bright glowing effect to emit from the lid, which will then spring open and disgorge a total stranger, someone not recognizable to ANYONE present --hired ahead of time to wear my clothing (which will of course fit him horribly). This stranger will clamber awkwardly out of the coffin, stumble uncertainly about the room and ask people at random in total seriousness about his hair colour or the shape of his ears, and then wander out of the funeral home, still muttering incoherently to himself.
