There's nothing more awww or that lightens up your day than kittens' buttholes. I'm not going to smell them like I would enjoy smelling a puppy's breath but it's no less adorable.
"How's your day going?"
"You know what? It's all rainbows and kittens' buttholes. It's good."
I'll make a point to say that to the bank teller next time they ask.
