Why do humming birds hum?
Because they forgot the words.
"From the moment I picked your book up until I laid it down I was convulsed with laughter!"
"Wow, I'm glad to hear that."
"Someday I intend on reading it as well."
"Come on now, a child of five could understand this!"
"I'll tell you what, why don't you go fetch me a child of five!"
I never forget a face...
But in your case I'll be glad to make an exception.
