These meme-thingies are often works of sheer brilliance. This one combines scathing humour and ominous warning. I would bet you a dollar to a donut that if Henry Ford or Lee Iococca were alive today, they'd put that poster up in their offices and look at it every day. The message hidden under that snark is 'If you don't take care of your customers - somebody else most certainly will.'
Then of course, there's Micks and Paddies like Irish who will split the difference and take a ford chassis and dump a fire breathing small block Chev into it!
Goddammit. I was going somewhere with this, and now I've lost my train of thought!!! Stuff like this is why it is still completely legal and politically correct to discriminate against the Irish. What in hell was I babbling about...? St. Paddie's day...???
