With enough twisted logic, anything can make sense.
TEXT OF COMIC:
Ghost movies are so stupid. The physics doesn’t even work.
If that guy’s a ghost, and he can walk through walls and everything, then how can he sit on that chair without falling through it and landing on the floor?
Why would he land on the floor?
Good point. He should fall through the floor, and through the ground, and… Are all ghosts trapped in the center of the earth?
Well, if gravity works on them. No reason to assume it does.
Maybe he’s sitting on the chair because he can hover indefinitely in any position he likes, and he happens to like sitting on a chair.
Stop making stupid movies make sense.
MOUSEOVER TEXT: boo
That’s what I always assumed about ghosts – that they can hover indefinitely and when it looks like they’re sitting on something, they’re actually just hovering so it looks like they’re sitting.
Yeah, it’s really the only explanation that makes much sense.
Another possibility: being able to pass through stuff is voluntary, they can lean against a wall if they want, or pass through it if they’d prefer.
Also a good possibility. Though ghosts in movies often seem to be unable to act as if they’re substantial (trying and failing to give someone a hug, etc). I think many of these movies lack consistency.
