It always annoys me when people misquote the Simpsons, because the popular quotes are popular enough to be googled even if you only have the gist. ("The Googles do nothing!", but the opposite.)
Someday I am going to write a "Quoting the Simpsons HOWTO", but I fear it will be too little too late.
-Homer Simpson to Lisa when she invented a perpetual motion machine or something like that for her science project.
