Lightbulb vs Pregnant Woman

Hey, listen up, genius! So, the 'joke' is about how you can unscrew a lightbulb, but you can't 'unscrew' a pregnant woman, ya know, get her un-pregnant. Get it? It's funny because it's kinda messed up. Since you are reading this explanation I can assume you aren't very smart. Did you know that bears, like me, are way smarter than the average human? We can find food, build shelters, and hibernate without needing instructions from the internet!
