So I used to teach Biology. And we did a question answer session about sex after getting through mitosis. One of my girls asked me about birth control pills - Do you take them every day or just when you have sex. After emphatically dealing with that misconception, Manny - who I will remember for the rest of my life - say "Hold up miss, hold up. You're telling me, there's a pill girls can take.... and they don't get pregnant?" "Yes, Manny." "WHY ALL THESE GIRLS PREGNANT THEN?" I will never forget the look on his face.
