Who's the stinky one?

A common question in this household. Sometimes all you have to do is look for the one making a face. That's the tall-tell sign. Usually followed immediately by the shit-eating grin. When they're all playing together, you just grab one (usually the fussy one) and you got a 1 in 3 chance of being right. Of course, if you come back and the smell is still lingering, you probably got another one. A few times, I've hit the lottery with all three. Lucky me, eh? Today, Mommy's camera came out and soon after came the question: Who's the stinky one? It didn't take much to figure this one out.
