Is that a grenade in your pocket?

Mardin Azad Amin found himself in a tight squeeze last week when security at O'Hare Airport discovered a suspicious-looking object in his luggage.

So, Amin, 29, handled the delicate situation this way: He told security the object was a bomb.

The security guard then asked Amin to repeat what he'd said to a supervisor. This time, Amin was chuckling as he spoke, prosecutors say.

In fact, Amin was trying to disguise the fact that the black object - resembling a grenade - was a component for a penis pump.

Amin eventually told investigators he'd lied about the object's true use because his mother was standing nearby when the object was discovered and he didn't want her to know about it.
