Fraternal Twins Puns

....and the second one Duplikate.

Fraternal twin sheets

So my step dad, mother, and I are on our way home from a pint night tonight when we got onto the conversation of twins. I was going back and forth with my mom, who as a nurse was giving insightful comments on the subject. My step dad quips in and asks if there's any specific parts of the US that are prone to fraternal or identical twins. We both are kinda confused for a second, and my mom says it's not a geographical thing but genetics. He then says he would have thought Minnesota would have been the place. I lost my shit. My mom was confused until she realized it was a baseball dadjoke.
