Why do ghosts wear clothes? HOW do ghosts wear clothes? Is there some sort of afterlife boutique?
Are you stuck with the clothes you were wearing when you died? What if you dropped a slice of pizza on your chest earlier that day? Do you have to go from your death until Jesus returns saying "Yeah, I know, I dropped a slice of pizza right before the truck hit me" over and over?
Can you at least trade clothes with other ghosts? "I'm SO tired of these khakis! I've been wearing them for 248 years." "Sure, I'll trade you those for this dress suit for a few years."
