Browsing the blogsphere today lands me at "15 (Painfully) Unforgettable cartoon themesongs". Hmm, I must be getting old. I look at most of these as "Yeah, I remember watching that".
Transformers? He-Man? Tiny Toons? Animaniacs? TMNT? Batman the animated series?
Enjoy. The links, after the jump, are to YouTube (mostly) for the opening credits.
