SCOTT SIMON, host: A man named Ed Mickolus joins us now. Two spies walk into a bar. One spy says to the other...
ED MICKOLUS: I'm sorry, Scott. You're not cleared for that punchline.
(SOUNDBITE OF LAUGHTER)
SIMON: Mr. Mickolus is a 33-year veteran of the CIA and a former stand-up comic. He's now written a new book called "The Secret Book of CIA Humor."
Thanks so much for being with us
MICKOLUS: Hey, just delighted to be here.
SIMON: Is that a smile face on your CIA I.D.?
