I've always wondered about this piece. Is he asking for and giving permission to take the booty, since the dead can't?
No, it's more a reference to an old routine done by a ventriloquist named Senor Wences. He'd ask his puppet "Okay?" And then he'd open a box and the puppet would say "Alright!" In this case the Ghoul is just talking to himself (mostly). Kind of like the ventriloquist, actually.
I liked this, has the right amount of undefined creepiness I think.
I always loved his "Oh shit!" face in that last panel XD
