The Dangers of Pornography
Tim already noted & quoted The Atlantic's Zarqawi feature, but he didn't mention this part:
Despite their enthusiasm, al-Zarqawi, al-Maqdisi, and Abu Muntassir did not appear to be natural revolutionaries. Their first operation was in Zarqa, in 1993, a former Jordanian intelligence official told me, when al-Zarqawi dispatched one of their men to a local cinema with orders to blow it up because it was showing pornographic films. But the hapless would-be bomber apparently got so distracted by what was happening on the screen that he forgot about his bomb. It exploded and blew off his legs.
