Hell no.
If I was a ghosty thing, I'd have more fun things to do. Especially if I could still move physical objects.
Plus, funerals are incredibly boring to me. Even without the risk of being bored to death, I wouldn't want to go there. Especially since I don't really care what the people there say about me.
On the note of boring funerals, I want mine to be awesome. I'm thinking that my body should be shot out of a cannon, with a few flares in my midsection. Then, when I'm a good thousand feet in the air, heat-tracking missiles are launched, and my corpse gets a good sendoff. And then a rock band will dig themselves up out of the ground and put on a show. As a finale, the whole cemetery would then be annihilated in a nuclear blast. Because I don't wanna be a dead floaty thing on my own! It might get boring.
...would any of you like an invite?
