It’s the best defense against killer rabbits and this past weekend, a prop replica of the Holy Hand Grenade of Antioch led to an English pub being evacuated according to the Daily Telegraph.

Water company engineers found the suspicious looking object when they lifted up fire hydrant cover during work 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.

Bomb experts were called in and spent an hour examining the device before determining it was a harmless replica of the prop from “Monty Python and the Holy Grail.” Replicas can be purchased on e-bay according to reports.

The spokeswoman for Islington police confirmed that the device was a toy and that had been no danger to the public

Local businesses criticized the police for taking so long to realise there was no threat.

Alberto Romanelli, owner of the Windmill pub that was evacuated, said: “I lost a good hour’s worth of business.”
