Mr D famously took on one reinforced concrete chimney. IIRC it was somewhere like Dartford or The Isle of Grain.
Being Mr D he was going to burn it down the old school way and so they started to 'weaken' the structure by chopping/undercutting on one side. Part way through and white flakes began fluttering down. Looking up confirmed it wasn't snowing.
'Run!', said Fred. 'We're not in charge of this bugger!' They barely got clear before the 400 foot structure collapsed, luckily in the spot predicted.
He had the chutzpah to ask for a bonus for completing the job ahead of schedule!
