Super Dragon and all round multi-millionaire keep fit fanatic 'I'm not a bit vain' Duncan Bannatyne shocked his fellow Dragons this week in Series 14 of 'Dragon's Den' when he actually agreed to invest in one of the proposals.

Duncan, 37, famous for his catchphrase 'I don't see anything there worth giving any thought to, and for that reason I'm out, ' bluffed the other Dragons and said 'I'm in!' and offered the sexy young lady whatever she needed.

Peter Jones collapsed, Theo Paphitis's teeth fell out, and even Deborah Meaden smiled. Only James Khan, the ex-Pakistan cricketer remained calm.

He said to Evan Davis, the unfortunate looking presenter, 'I find it facsinating that Duncan only ever shows any interest when it's a young attractive girl involved. He's a rum fox Mr. Bannatyne, with his lovely black hair and cheeky smile, I can see why he thinks the ladies love him. This investment for a share in 'The Cheeky Thong' company is right up Duncan's alley. I've never seen him so excited during a pitch, he was like a child in a sweet shop looking at the 2 girls. It's pathetic really. He's old enough to be their Grandad. '

Duncan later said he was over the moon at investing in thongs, and looked forward in particular to the Bannatyne range for the older, more reserved gentleman who still likes to 'announce his entrance'.

'I'll certainly be wearing them, ' said the Cheeky Thongs new owner.
