Now, I'm not as bad as my mother who would often call over a poor, unsuspecting waiter to complain about a typo or grammatical sin on the menu. It didn't matter if it was a fancy French restaurant or a truck stop. This usually had to do with a missing or extraneous accent mark, though even I had to agree when "Chicken Franchise" showed up on a menu in the Poconos when what they meant was "Chicken Francaise."
I also remember my dad talking about grammatically incorrect advertising slogans like the old cigarette tagline "Winstons taste good, like a cigarette should." Of course it should have been "Winstons taste good, as a cigarette should."
This got me thinking about current or recent advertising that plays fast and loose withe the rules of grammar. I'm sure you can think of others but here are a few along with how they should read.
Eggo Waffles: Leggo my Eggo -- Let go of my Eggo
Milk: Got Milk? -- Do you have milk?
Subway: Subway, eat fresh -- Subway, eat freshly
Apple: Think Different -- Think differently
McDonald's: I'm lovin' it -- I am loving it
Staples: We got that. -- We have that.
What others can you think of? (and yes, I just ended that sentence with a preposition).
