(1) Worst Episode :
this overuse of this expression adds up to the worst newsgroup ever. Goddamit people. This plastering of catchphrases is almost as bad as the first two seasons.
The simpsons should do an episode devoted to all the unimaginative geeks (not nerds, nerds are smart) in this group. It could be an invasion of rat that follow the pied piper (played by moe) bumping into each other, drunken-like. Everytime they hit, they could spew a catchphrase. Moe drowns the whole lot and springfield lives happily ever after.
(2) a wizard did it:
the fact that it needs to be used at all is a joke in itself.
