Haven't heard of the Acai berry. but on a somewhat similar "new product" theme...

Bloke I met on the bike the other day was gee-ing up some new gel product that he was distributing, Gave me the website to check out and when I got home & looked it up it was basically an Amway type set up with "sports nutrition" products. Thanks mate, please don't make me waste my breath if you see me on the road again.
