Lol.. I had to do this for my 3 month old baby once. The poor little guy had a bit sticking out and it wasn't coming out. He hadn't pooped in 4 days, which for a baby is pretty crazy. So, I removed the "plug" very gently with a the tip of a rectal thermometer. The "plug" was weird and very dry and sandy looking, then some more, and more, and then all of a sudden it was like a soft serve chocolate ice cream machine, it just kept coming out! The little guy was screaming and giving it all he had, I felt so bad for him, but also happy. And when he was done he had this really tired smile and looked so content. Then he passed out. (Babies do that a lot anyhow) Thank god baby poop doesn't stink too bad.
TL;DR: I'm going to have a great story to use as blackmail material when my son gets to dating age. And as a bonus, it involved poop. And poop is funny.
