Hey i like anniemaniacs!
When do we want her? Annie time, annie place.
To the earlier guy that said "lunatic" and "retarded" were analogous, i gotta actually defend the Luna camp here.
Lunatic generally has a more light-hearted connotation, and while it's negative, its negative in joksey-folksey way (geez, you're acting like a lunatic!). On the other hand, retarded is almost always used as a strong pejorative(outside of physics and music)- which is probably why many people seek to have it be considered archaic.
