What was the last thing that went through Aiden's head before he died?
His elbow.
Listen up, buttercup! The joke is dark because Aiden died. Get it? The punchline is that his elbow went through his head. That means whatever killed Aiden, like a car or somethin', forced his elbow into his head. Now, I know you ain't got no brains, but I hope that made sense.
What?
???
Why.
Is that even possible?
