Sibelius walks into the doctors and says 'Doc, I haven't had a bowel movement in a week'. The doctor gives him a prescription for a mild laxative and tells him 'if it doesn't work, let me know'. A week later Sibelius is back 'doc still no movement'. The doc says 'hmm, guess you need something stronger', and prescribes a powerful laxative. Still another week later and Sib is back, 'doc, still nothing'. The doc now worried says 'I need to investigate just whats going on here, what do you do for a living', 'I'm a composer' says Sibelius. The docs face lights up 'thats it! heres 10 quid, go get something to eat'.
