"So, K and L, what happened to the bag of kitten chow?"
K: "I don't know. I can't possibly imagine I am shocked and offended - offended - that you might consider that I had anything to do with it. No, I did not, on my own, chew the hole in that bag of kitten chow and eat half of it."
L: "I don't know, either. Does this look like the face of a kitten-chow-bag-chewer? No, I too can state categorically that I did not, by myself, chew into the bag of kitten chow and eat half of it. I simply can't imagine how it happened."
Hmmmm - Dial M for Mischief.
