Watch out for the Men in Black - just like the films, only real.

Unsuspecting workers on a construction development in Washington got quite a response when they accidental cut through a fiber-optic cable.

Within moments 3 SUV's (black of course) pulled up and 6 men in suits jumped out. "You just hit our line". Whose line was never quite revealed but one could probably assume it was a 'black line' (private, unlisted, secure) belonging to the FBI/CIA/NSA (delete as applicable).

Hollywood would be proud.
