For any fan of Misha to believe what he supposedly said in today's panel about taking a prank too far, they must either be new to the fandom, or have absolutely no memory of these stories before.
Let's be honest, the fans who think Misha's telling the truth "this time" absolutely know it's not true and are using this new story to persecute Jared, once again.
For those who haven't seen, here are the tweet reports from Misha's panel. Obviously, video will provide proof, but there are enough details to get the gist and these aren't the standard Misha-fan con reporters that like to lie about or twist what was said.
So, the original story about Jared taking a picture was told by Misha on the Inside of You podcast (see below). There was no zero gravity dive. Misha simply forgot to lock the bathroom door. Jared took a picture of him on the toilet, not naked and with no urine in sight. And yes, in retaliation, Misha flushed Jared's phone... the one that had the only pictures of his son, Shep's birth.
As for the getting knocked around, being covered in urine, etc. That comes from a trip Misha took with Rich, Rob, and Matt down to Australia for a convention. Misha tells the story here:
Matt, Rob and Rich have all corroborated that story here and here. It's actually a pretty funny story on it's own.
So, Misha put together some mash up of these two stories, making him the victim (once again) of a dangerous stunt supposedly perpetrated by Jared (which no pilot would ever agree, especially without all passengers belted).
If you haven't caught on by now, Misha lies. And he lies for a purpose. Most often, it's to engender sympathy from his fans so they'll continue to see him as poor, picked-on Misha who can related to them because they are also the 'outcasts' in their world. And if he can relate to them, then they'll continue to give him their money.
You may also wonder why Misha frequently references Jared as being the one to prank him (and often, the only one). One, because he needs Jensen as the other half of the Destiel pairing, which is another way to keep his fans dropping money in the coffers. And two... jealousy. From past stories and behavior, it's obvious Misha's jealous that Jared is as successful as he is, someone who never went to college but has worked steadily for over 24 years in an industry rife with unemployment. Misha likes to say things that imply Jared's only gotten by on his looks and not any kind of talent, but we know that's simply not the case. Actor's aren't employed for that long and that consistent on their looks alone. Talent and hard work are also needed, two traits which Misha obviously doesn't have, so he resorts to stringing along his dwindling fanbase with any story he can, regardless of it's veracity or whom it may hurt in the process.
Finally, Misha knows exactly who his fans are and how his fanbase takes the things he's said, so if he's ever called out and says he was joking and that people misinterpreted what he said, he's lying. And I'd say that lying was the only thing he was good at if it weren't so easy to debunk the lies.
