jenx67.com is spot on when she writes that Grimace will always be an important Gen X icon. She pits him against the GenY's big purple friend, Barney.

This photo just came up when image searched "sexy grimace" (don't ask) and i made me laugh till tears were streaming down my face - Just please show Grimace some love!
