Peanut Butter and Jelly?

Alright, listen up, chucklehead. This joke is dark, like your future. The setup is all innocent, like peanut butter and jelly, then BAM! Afterbirth! It's morbid because it involves birth, which is supposed to be happy, but afterbirth is... well, it's kinda gross and definitely not what anyone wants to see or think about during a sandwich craving. You probably scream when you see vegetables, so maybe this isn't too far off for you.
