Osama Bin Laden's Secret Cousin

Alright, listen up, buttercup. This joke is playing on the similarity between Barack Obama's name and Osama Bin Laden's name. It's implying they might be related, which is a wild and based stretch considering one was the President of the United States and the other one was a terrorist. It's a play on words and, well, some might call it dark because it's alluding to Osama Bin Laden, who ain't exactly a barrel of laughs.
