mpg happiness bumper stickers and t-shirts

I think we have all seen the Kia commercial calling for people to achieve MPG Happiness with their new line of SUV that gets only 21 city/29 highway. I guess that is good for a SUV, but to truly achieve MPG Happiness try a hybrid like the Prius. When I'm getting 53 MPG for my trips to work I can honestly say I have achieved MPG Happiness. If you have also, then try this bumper sticker out.
