Here's a funny one:
An Egyptian man from Cairo routinely donned a full Islamic niqab to visit his long-time mistress. He camouflaged himself to prevent her neighbors from gossip, and probably because it's hard to have an affair with someone after she's been stoned to death.
The 30-year old man was outed after a woman on the carriage noticed his um, manly footwear poking out from under his veil, and screamed for security to unmask him.
Now comes the not-s0-funny part... If this yahoo can dress in a head to toe veil and sneak around almost indefinitely, then what would stop a terrorist from doing the same?
Burqas and the like should be illegal in free countries!
