Regretted Abortion

Okay, listen up, you big dummy. This joke is dark, like a cave full of bears with no honey. The person is saying they regret their abortion, right? But then, instead of giving a normal, sad reason, they hit you with 'I didn’t know child labor was an option.' The humor comes from the shock and the absurd comparison. You, my friend, probably didn't see that coming, because you're about as predictable as a bear's hunger for salmon. It implies they would have preferred exploiting their child for work over not having the child at all, which is, you know, messed up, but that's what makes it a dark joke. You get it now, or do I need to draw you a picture with crayons? You really are a simple creature, aren't you?
