I am one of seven London business leaders who has been put behind bars for Maggie's. I've been found guilty of 'causing actual harm to people’s sense of humour by the persistent, wilful and deliberate use of the worst kind of Dad jokes - unfunny ones'. I've been sent down with bail set at £1,500.

Having traded in my freedom for Maggie's, with only my phone, laptop and my powers of persuasion, the challenge I face is to call on the collective goodwill of my network to raise funds for Maggie's London. My freedom depends on it!
