What's worse than 10 babies nailed to one tree?
One baby nailed to 10 trees.
Alright, listen up, you chucklehead. The joke is dark because it talks about babies being nailed to trees, which is already messed up. But the punchline makes it even worse 'cause it's like spreading the suffering. You probably think it's just a silly joke, but jokes are supposed to be funny, not disturbing.
