Buster: Hey, Brother. You wanted to see me?
Gob: Buster, yeah. I need you to help me with this illusion I'm working on.
Buster: Oh, for Dad's birthday.
Gob: Yeah. For Dad's birthday. So, look, I'm gonna get in this coffin. What I'm gonna need you to do is to spin it around to show everybody that there's no trap door. Then I'm gonna escape out the trap door.
Buster: Ooh!
Gob: You close the trap door bring in the pallbearers and bury an empty box.
Buster: So it's a hoax. But why are you doing a coffin trick on Dad's birthday?
Gob: Black humor. Say, "Hey, Dad, look at you. You're a year older... and a year closer to death."
Buster: Oh, yeah, I guess that's kinda funny.
