'Wonder Years' Winnie Cooper, Danica McKellar, strips in Maxim? Nooo!!!

It's both the end of the world as we used to know it and the fulfillment of a million guys' secret fantasies.

Danica McKellar takes her clothes off and poses in sexy lingerie for Maxim's June issue. And we've got the proof.

But If you have to ask "who?" just move on to another blog post. This is not for you. This is for " Wonder Years" fans and "Wonder Years" fans only. No one else would understand how devastating this is.
