Yeah, aware that genre's been done to death - much like the protagonists Dad and the train.

I'm sure there was a cut away segment in one episode that showed a similar past/present/what if/if only scenario that ended with Peter/Brian/Stewie/whoever taking advice from their past self only to end up with them having taken the right path as they were sitting pretty with some fancy hookers who were letting them do INSERT HERE (can't remember what) to them in the name of money/bad taste as a show of Peter/Brian/Stewie/whoever's success.
