One day while a little boy was at daycare and was playing with all his other friends when, he happened to notice one of the baby girls being changed.

Curious the little boy started to stare at her wondering why she was different. So the little boy went over and asked one of the teachers.
not knowing what to say the teacher replied she just has two butts.

Later at home when it was time for him to get all cleaned up he gets in the shower with his mother. Once again curious the little boy starts to stare at his mother, after a while the mom asks him "what, what is wrong, why are you staring at me". The little boy replied "mommy why does your other butt have a mustache."
