When I was a 16yo apprentice engineer (Yes, I DO have a long memory) three apprentices decided they'd attempt to remove a blacksmith's anvil from the secret and secure MoD experimental establishment where we worked.
They made a halter, placed it around the neck of the strongest and suspended the anvil between his legs and hid it with a long coat.
The other two supported him past the MoD police guards, explaining that he'd taken ill and they were helping him home.
They were caught when they tried to return it
