Ammon's Kidneys

So tonite it was Zack's turn to read and he says:

"Aaron told the king he was Ammon's brother. The king had been thinking about Ammon's kidneys and about what Ammon had said to him."

I say, "Whoa whoa...Ammon's what?"

"Ammon's kidneys."

"Are you sure?"

"Yep."

"Can I see?"

I took a glance and of course saw that it said "kindness," not "kidneys." But, he was reading quickly and didn't quite take enough time. We corrected him and he went on and Robb and I chuckled till we about cried.
