This isn't Photoshopped, folks; the satellite imagery is from 2004 (but was only made available recently). In Hazleton, PA, prior to the start of the football season a few enterprising jokesters decided to pull this prank, I believe with fertilizers or chemicals or something. I'm also pretty sure the stadium (Harmon-Geist) quickly replaced the grass with artifical turf.

Their mascot is the Cougar, btw. Makes it rough for cock jokes, but I'm sure we can all manage.
