They’ll be really upset when it rains and the grass has yellowed from being covered in paint..............
The only reason the Cerne Abbas Giant is still there is because the government goes out from time to time and re-chalks the lines. It would be funny as heck if somebody re-chalked the Giant Homer every six months or so. Then after 100 years, nobody could remove it because it would be sufficiently old.
The grass is already greener on Homer’s side!
