Haven't had time to read them all, but someone referred to 'Sweet Fanny Adams' back there. There was a murder victim named Fanny Adams, and I think the body was either never found or found dissected. WW1 soldiers used to refer to any unrecognisable dish served up to them as 'Sweet Fanny Adams'.
We had 'If you don't get a haircut soon we'll have to buy a violin!'
And one that came to minnd on seeing one of Tony Blair's sons with an excuse fo a moustache, 'Never cultivate on your lip that which grows wild round your bum!'
