There are some things that just should not change. Michigan football should always have the winged helmets. Porn should always be no more than three mouse clicks away. And the Cookie Monster should always be a monster about, well, cookies.
Alas, it appears he has fallen victim to Them What Want To Suck All The Fun Out Of Everything:
My beloved blue, furry monster — who sang "C is for cookie, that's good enough for me" — is now advocating eating healthy. There's even a new song — "A Cookie Is a Sometimes Food," where Cookie Monster learns there are "anytime" foods and "sometimes" foodsMy God, people, is nothing sacred?
So wait... those are wings???
The best commentary I have seen on this is in PVP here (especially the last panel). The comic after that is also pretty funny as a side note on this issue.
