My OH uncle has been rude throughout my pregnancy, whenever it's brought up he asks, "don't you know what causes that?" And usually I laugh it off but due to me hearing it at least monthly for the last 7 months, (I'm 9 months along,) I got a little pissy.

"Amazing sex with my fiancé that leaves his woman begging for another round as soon as it's over, would you like some pointers from him? Do you know what causes pregnancy?"

While his family laughed and joked about him not knowing what hole would lead to a baby and asking him if he knew the difference from the ear canal and a vagina was funny, yet later when he tried to demand an apology was ridiculous.
