I WAS half-expecting some hopeful young business-man to pitch a brand-new invention called the wheel to the fearsome dragons on last night's Dragon's Den, such was the calibre of the inventions.

Innovations up for scrunity were a device to untangle wet or dry hair (erm, a comb anyone?); underwear that pops from all sides for ease of use (how much difficulty have you ever experienced taking your underwear off?) and an odd apron to make bathtime easier for parents (what's wrong with a towel?) I'm not surprised the dragons were mostly disgusted at the offerings put before them. I wouldn't have given 50p to have a stake in any of the companies on offer.

The show had changed dramatically since it started. It used to be about poor entrepreneurs and inventors coming on and presenting wacky ideas.

Now it seems the dragons are in danger of becoming caricatures of themselves. Not a week goes by that Peter Jones doesn't launch into some cutting tirade, ending with the infamous words "I'm out".

Never a week where the dragons don't act initially impressed, then turn like a pack of angry wolves when the person asking for cash fails to tell them precisely how much they plan to make from the American market in the next 10 years (or some equally difficult question).

I love this show, but let's hope it doesn't become little more than a pantomime.
