A while back, Mitchell and Webb did an awesome sketch about people cleaning their tongue.

It is funny. Now. It seems the norm that you need funny ridges on your toothpaste that could aide bulima but are really designed to scrape off that bit that you get after you drink a full fat cola-flavoured beverage. So they need something else. And that requires a special toothpaste. Ladies and Gentlemen, I give you Aquafresh Ultimate. Not total, not complete, but ULTIMATE!

A toothpaste, that judging by this commercial, uses technology. Now, before you get confused, I couldn't find an English-speaking advert, but I don't think it mattes. Check out the graphics!

I've used this, as it was on offer in Asda for £1. It's rubbish and it makes your mouth fizzy making the first work cup of coffee of the day even less fun.
