Worst advert ever

I saw an advert on a tube train today for Vicks First Defence, which went along the lines of "A stinking cold is the last thing you want for Christmas. Vicks First Defence fights the cold virus in the early stages and may prevent symptoms developing. In fact, 77%* of people who used First Defence said they didn't get a cold. Happy Christmas."

The asterisk leads to some very small print saying "2006 satisfaction survey of 90 UK users."

So let's get this straight. Out of 90 people who used this product last Christmas, TWENTY of them developed a cold over the Christmas period? What percentage of people would normally get a cold over that kind of timespan? I'd be very surprised if it's as high as 23%. It seems to me that this First Defence stuff actually makes it MORE likely that you'll get a cold! And they're using this statistic for advertising purposes?

Anyway, that rant was the main reason I've come to this internet cafe/barber's shop in the heart of London tonight, but I suppose I should also mention that the chimp memory filming went very well too - I see they made the BBC news tonight, too, so I'm sure it will be old news by the time the documentary makes it to your screens, but you will have the fun of seeing me attempting the same memory test and scoring significantly worse than Ayumu the chimp. It's going to be great!
