Last week a national ISP had the mis-fortune to have their banner ad touting "The only thing slowing us down is the speed of light." be juxtaposed with a New York Times article titled ""In a Major Breakthrough, Danish Physicist Slows the Speed of Light" which reported on a scientist who had succeeded in slowing light to a paltry 38 miles per hour.
They now have a new banner ad out (this is for real):
"The only thing slowing us down.... ...is the occasional group of physicists."Touche!
