[ That little quip coming out of the brother without a name takes Rex by surprise and startles a true laugh out of him. There's no mistaking that one, even when it's muffled by his hand.

The kid's got a sense of humour. Who knew? ]

Can't say I've ever thought about it like that, [ Rex says, regaining his composure and dropping his hand to his side, though there's still good humour sparkling in his eyes and a smile tugging at his lips. ] We can't be too hard on them. Not everyone's made as well as us.

[ Rex watches as one, at the top of inflatable stairs, falls not on his ass but directly on his head on the baloons below, limbs akimbo and loudly squawking. It's a sight. ]

But they can't possibly be made that poorly either. It's like the man's never seen stairs in his life.
