It's been only three days since the shockingly sad demise of popular Family Guy character, Brian Griffin and already rumours of him returning have gone viral. Several posts, tweets, theories and petitions regarding the top dog's return are doing the rounds of social media.

However, the most mysterious development on that front has been a website called "Brian's Announcement" which suddenly appeared online on Tuesday. The page contains a countdown clock, which was set in 10 days' count, and promises a "special announcement from Brian" when the timer strikes zero. It includes a discrete text that reads "A Fox Production," making visitors believe that 20th Century Fox TV has set up the site for Brian's return.

For the record, a 20th Century Fox rep tells TV Line, "The producers have confirmed that the 'special announcement from Brian' website is a hoax and was not created by anyone connected to the show, studio or network."

But even before the site surfaced, fans and some members of the media, have questioned whether Brian's passing is an elaborate publicity stunt.

According to TV Line, the show's 2013 Christmas episode might bring back the dog. "Consider the plot of the animated hit's Dec. 15 "Christmas Guy" episode: Stewie hatches a plan to get 'the one and only thing he wants for Christmas.' Since we all know what that is — his BFF, alive and kicking — it doesn't take a rocket scientist to do the math," the report states.

Although that does seem like a plausible option, another theory one can explore is that perhaps Brian will return in The Simpsons-Family Guy crossover episode. Seth MacFarlane (voice of Brian) has appeared in an episode of The Simpsons, and Dan Castellaneta of The Simpsons made an appearance on Family Guy, but that has been the extent of it to date. Resurrection of the Griffin's dog at that point will only add to the epicness of the mash-up episode.
