I used to believe that my grandpa was pregnant... he was all muscle everywhere else except for his very round belly. When I couldn't take the weight anymore, I had to ask him why his water hadn't broken yet... I had to explain to him why I thought this, too. He laughed and said that boys stayed pregnant longer than girls.. it wasn't until I was 8 or 9 that I finally found out that it was a beer belly..
I still remember checking him every day... *sigh*
