Discovering only pee when changing a diaper, several times in a row. Presumably the other parent (or babysitter/grandparent/whoever) was not so lucky.
I've been dodging the brown bullet for a week now. Baby and I have worked out the perfect arrangement.

When your taking a shit and there’s gas behind it and the shit is in the front and when you push it, it goes flying out like a bullet
My homie Jonathan just did the brown bullet a few hours ago
