You're not thinking like an advertiser. A farmer could mix 5 grams of grain into a 5 tonne vat of other non-grain chicken feed; the resultant chickens would be "grain fed", a literally-true statement that would stand up in court. I'm surprised at this lapse in your normally-reliable cynicism ;)

I think what that advertiser wanted to say was "vegetarian [or vegan] grain-fed".

While we're on this topic, my favourite (and a favourite of car dealers) is "Priced to Sell!"

Then there was a recent "Dilbert" strip. Dogbert is starting a new magazine. He says to the PHB: "Would you like to advertise in our magazine? We have between 1 and 2 billion readers!"

Later he confides to Dilbert: "I found a way to make 3 readers sound like a lot".
