London bus company, Metroline has been found running AdSense ads on its fleet of buses. Someone snapped a picture and posted in at DigitalPoint Forums, the day after April Fools Day. It is a pretty good picture, barely looks "doctor'ed" up. But yea, I doubt they are running real AdSense ads on those buses. :) Seems like a post April Fools Day joke.
Not bad, ehh? Forum Discussion at DigitalPoint Forums.
