I've never had a dog, so there was one advantage of having a kid I wasn't familiar with: it's someone to blame a fart or two on.
There are limits, though. Sometimes, when the limits of plausibility are reached--or exceeded--such as when your 2-year old, toilet training nephew starts running in circles around you saying, "I smell poo! I smell poo!" but your kid is nearby, but clearly out of range.
