Dragons' Den is where life-changing business deals are made. The five multimillionaire investors are looking for the next big money-making ventures, so any attempt by an entrepreneur to deflect a question or change the subject can lead to some choice words and a quick exit. This week in particular the Dragons seem to have got out of their million pound beds on the wrong side. Tempers flare when one entrepreneur offers just one per cent of his business, valuing it at 15 million pounds; hackles are raised by a toastmaster from Staffordshire looking for investment in his 'male intimate wipes'; and the Dragons live up to their name when deciding whether to invest in an online store for second-hand goods. But can any turn it round and secure the investment they need? Also facing the Dragons are a TV stuntman pitching his horror-themed paintball experience, a husband and wife with a new DIY product and a man from Birmingham who believes his darts invention is a world first.
