Do all Joss Whedon creations take place in the same reality?

Odin was the CEO of QM&P then, unless the present is Odin jr. I think what Jesse saw was Odin's sex doll made of raw meat.

All shorts on that list (with the notable exception of Crowing Pains - which was found out to have it's copyright renewed in 1974) are still under the public domain. However, I've heard from some sources that Warner has placed copyrights on the restorations used for the Golden Collections.

It takes place from 2364-2370 A.D. 95 years after the events of the original TV series, 94 years after the events of the animated series, & 71 years after the events of the Undiscovered Country movie.

Season 1 has been confirmed to take place three years after The Battle of New York.

The anime is paced far slower than the manga, and features a number of "filler" sagas that weren't in the original manga. These had to be added into the anime to keep pace with the release of the manga, which was still being put out as the anime was being made. As these fillers were created with only minimal involvement with Akira Toriyama, they often contradict major plot points of the series. For instance, the entire Garlic Jr. Saga was a creation of Toei Animation, and does not appear at all in Toriyama's manga. Some filler segments are merely fights from the manga that are extended, as well as drawn-out extended scenes of characters powering up. Amusingly, most of the complaints people have about the show stem from anime-only filler and aren't problems that exist in the original manga.

Tom Fontana has always said that he willingly sacrifices factual accuracy for dramatic purposes. In particular, Fontana has indicated that he believes that maximum security wings like Emerald City are significantly safer than depicted on his show. Chuck Zito, who plays Chucky Pancamo on the show, and who is one of only two cast members(the other is 'muMs da Schemer') to serve prison time, has commented that Oz is a heightened version of the reality of prison. The amount of violence, sexual assaults, and drug abuse which is depicted on the show is far in excess of reality, but most of the activities depicted have a basis in fact.

In the final episode when Joey buy Monica and Chandler and new baby chick and duck, it is revealed that Joey was told they were sent to a farm when they got old, obviously protecting Joey from the fact that they either died or were put down. The last time you hear from the Duck is in an early season 7 episode where Joey says the Duck was throwing up all over the place and he did NOT eat Rachel's face cream.
