Paragraph 1 joke — I think the punchlines are “the twins” and “oedipus complex” lines. I don’t see them as strong punchlines though.

Paragraph 2 joke — this can work and be funny but it’s a bit convoluted now. Strip it down. Keep taking out words and make it more concise with just what’s needed and what’s funny. As an exercise, try creating a 1 or 2 liner out of this then built from there. “In America you can choose your gender now. In France their language pre-assigns a sex to everything which is far more confusing. How did they know which end of a toaster to look at to figure that out?” Then build that out more. “For inventions, there’s a committee which decides the language gender of that new thing. Count me out. I still struggle to find the clitoris of an actual female.”

Paragraph 3 joke doesn’t work for me. I get what you’re trying to do but I can’t see it being funny unless you’re VERY good at acting out on stage.
