My ex had a small safe in his work. He pretended to jam his thumb in it and grasped his hand while dropping a slightly mashed raw sausage, covered in fake blood on the floor while squeezing the tube of fake blood with his 'injured' hand in order to get the right spurting look. Most of the staff were in on it, but the poor guy who wasn't nearly puked/passed out.
The WORST was many years ago when Graeme Dene was a breakfast DJ on Capital in London. EVERY time check was an hour in front, and thinking I was an hour late for work, I rushed, fell over in the street, sprained my ankle and was off for a week. Yeah OK I shoulda checked elswehere, but you trust them not to muck about like that, and when you think it's 8.30, you panic.
post - that reminds of my secondary school teacher who called a whole-school assembly to tell us that the school was going to teach only boys and the girls would be expelled. Funny to look back on now, but caused a hell of a lot of tears at the time.
I don't know if Radio 2 are trying to pull some sort of April Fool. But that is definitely not Ken Bruce talking now. My guess is Rob Rydon doing his Ken impression. Badly. Ken isn't Welsh.
