Jon Stewart blames himself for missing the Petraeus, Broadwell signs [VIDEO]

"There comes a time in everybody's life when you're faced with a choice -- whether you would like to have sex at your desk at work or remain employed," Jon Stewart begins his segment (aptly titled "Spyfall"), on Gen. David Petraeus' affair with his biographer Paula Broadwell.

The Petraeus-Broadwell affair and subsequent FBI probe -- now expanded to include Gen. John R. Allen, flirty emails and shirtless agents -- took everyone by surprise, so no one can blame Stewart for missing all the signs when Broadwell appeared on a January 25 episode of his show promoting the very biography that put her in the headlines.

"For God's sake, the title of her book was 'All In.' You might as well have called the book, 'What has two thumbs and is banging his biographer?'" Stewart says in Monday night's episode, which includes a collection of clips of Broadwell discussing the details of her relationship with the then-CIA director.

So did the nation's preeminent comedian-journalist miss a ton of obvious sexual innuendo? Decide for yourself -- here's Broadwell's original "Daily Show" interview. Hindsight is 20/20, but she does refer to their frequent runs together, one of Petraeus' so-called "mechanisms to get to know young people."
