Question: There was supposedly one episode that ended with SpongeBob, Patrick, Squidward, and Mr. Krabs all laughing in a boat. The laughing then silences, eventually to a stop.

Question: If Cordelia didn't actually wakes up from the coma how did everyone besides Angel see her? No one said "weird, we talked to and hugged her and all".
Answer: Everybody including Angel saw her. After helping them and then being left alone to talk to Angel, Cordelia says that the Powers That Be let her come back one more time to help them. After Angel gets a call saying that she died, he realises that it was her spirit that was helping them the entire time.
Question: Why is John's Farscape-1 module able to navigate wormholes where some other, more sophisticated craft, notably Peacekeeper Prowlers, cannot without liquifying passengers?
Chosen answer: It's never explained. John mentions a theory that his less technologically developed craft simply interferes with the wormhole less than the "superior" Vipers, but they never make a concrete determination on that point. But we also have to take into account the fact that Moya traverses wormholes with no ill effect as well.
Question: How did the streetcar, phone booths, and vending machines end up in the digiworld?
Answer: We are never told as to how they got there.
Answer: People who built the digital world most likely had them sent there. Gennai tells the kids in the last episode that the streetcar was from San Francisco, and he asked them to take it back for him.
Answer: I believe this is the Season 6 episode "Spongicus".
