London - (Big Bang Theory): Last Xmas Day his controversial penile dysfunction cure failed to light up underpants bomber Umar Farouk Abdulmutallab's y-fronts.
289 Northwest Airlines Flight 253 passengers were spared from a fatal splattering of Abdulmutallab's detonated genitals as a lethal mix of sodium pentathol/pentaerythritol tetranitrate merely farted into business class airspace.
This weekend Ibrahim Hassan Tali al-Asiri took the rap for yet another spectacular cock-up as a Yemeni cargo bomb destined for Chicago mayoral wannabe Rahm Emanuel's synagogue failed to explode to smithereeens.
Al-Asiri's fixation with exploding genitalia may be behind a pyrotechnic obsession going back donkey's years (don't ask).
In August 2009 he somehow persuaded daftass half-bro Ahmed to hide 1000 grams of lethal explosive PETN up his asshole attached to a detonator with a chemical fuse.
Ahmed then was granted an audience with Sordid Arabian security chief Prince Mohammed bin Nayef whom he tried to blow up for the 'crime' of suspected apostasy.
The fuse ignited, tearing apart the bomber's innards before gouging out a massive great big crater in the Interior Ministry's interview room.
The minister escaped unscathed - save for an utterly ruined Armani dishdasha and a subsequent course of anto-tetanus/rabies shots.
Carlos the Jackass is one sick bastard.
