Those who knew Umar Farouk Abdulmutallab are amazed at their former classmate's actions. The head of the engineering department in which Abdulmutallab was enrolled described the 23 year old as a "hard working student althought quiet. The only sign of any trouble was when he asked whether he could sign up for the Explosives in Pants workshop. We don't normally get many people interested."
Fellow student Alan Wicker remembers Abdulmutallab as a diligent worker although prone to eccentricity. "I remember he came up to me one day and said, 'I've got a bomb in my pants.' I said, 'Yeah, I also need to get laid.' He said, 'No seriously, I'm packing explosives.' I replied, 'Damn right, I call mine the Wrathful Cobra.'"
