Being a bit of a geek, I like to study the caveats and Ts and Cs scrolling across the bottom of TV ads when claims are being made. This is occasionally amusing - look closely next time More Th>n comes on...

But more often than not, the caveats reveal startling weak stats, especially for women's beauty products. This recent ad for Boots No. 7 Extravagant Lashes is a case in point. The screen grab below is taken from around the 18s mark.

56 women surveyed! 56! and only 47 agreed. What's the point?
