I actually believe this. I noticed that going in 3rd person while sitting in a boat changes the position your right arm is in (kind of tilted to the left). I dont see why this would be impossible with that glitch around.
I'm really going to have to ask for more evidence for the original claim before a thread can be made on it. As it stands this thread will just be a debate over whether this actually happened, with plenty of "Pics or gtfo" posts I don't want.
