I think your idea of a Lost Episode is probably something like Bart dying or Homer dying in some sick, graphic way.

Good news? There are lots of Simpsons Lost Epsiodes out there.

Bad news? The episodes are just regular epsiodes that never aired on television, possibly a bagged idea by the creators or the creators just chose not to air it.
