TSA and security officials observed that two of the Middle Eastern men intended for the flight had smeared Vaseline on their arms and neck areas — a common tactic among hand-to-hand fighters who want the advantage in the event someone tries to grab them or put them in a headlock. Covered by the greasy agent, they are better able to extricate themselves during close-quarters, hand-to-hand fighting.
Reminded me of when I used to play football and the recievers used to spray PAM on their pants to make them harder to tackle.
I hated those guys!
