"There's nobody here but us chickens," is the usual reply that I get from Kelly when I call out, "is anyone home?" when I get back from anywhere. He said it once, and I found it amusing, so now he says it to make me laugh. At least, I assume that's why he keeps it up.
Anyway, the other day...
Me: "Is anyone home?"
Kelly: "There's nobody here but us chickens!"
Me: "Why are the chickens indoors?"
Kelly: "They just are."
Me: "But chickens stay outside."
Kelly: "Not always."
Me: "Yes, they do. And, you know why?"
Me: "Because of all the feathers... They don't like to vaccume, and they'd have to if they were indoors."
