Monty Python prop causes bomb scare.

It's only a flesh wound. From Ananova:

Bomb disposal teams were called in and buildings evacuated after a Monty Python film prop was mistaken for a hand grenade.

Water company engineers spotted the object when they lifted up a fire hydrant cover on a street in Shoreditch, east London.

The road was cordoned off and a nearby pub was evacuated amid fears that the "grenade" could explode, reports the Daily Telegraph.

But after nearly an hour, bomb experts realised it was in fact a copy of the 'Holy Hand Grenade of Antioch' used by Eric Idle to slaughter a killer rabbit in Monty Python And The Holy Grail.
