I needed a test on if I'm pregnant. Then the doc said, "Take your pants down." Then he put his penis in my vagina and said, "Now you are pregnant."

Alright, listen up, buttercup. The joke is about a doctor who's supposed to give a pregnancy test but instead just, you know, does the deed himself. It's funny 'cause doctors are supposed to be professional and not use their junk for medical exams. You probably thought that's how babies are made. No wonder you are still single.
