RX: "What's wrong?"
Me: "I can't find it!"
RX: "Can't find what?"
Me: "Mas Ayoob sent me a review copy of his book, and I can't find where I put it."
RX: "Did you open the envelope?"
Me: "I read the book! 'Did you open the envelope?' That's a little harsh, don't you think?"
RX: "Well, sometimes people send you things and you don't open the envelopes."
Me: "They could be bombs!"
RX: "From Massad Ayoob?"
Me: "Good point."
RX: "Besides, that was long enough ago that any anthrax or smallpox would have died by now."
