He's a hobo! I'm guessing there will be some jokes to be had with that one. Side note: Anthony Hopkins is really good at looking gross.
I figured most of this story was taking place on another planet aside from Earth, but now I don't quite know what to believe. Joey pointed me to a post we did earlier this year which rumored Odin to have fled to Midgard to pose as an "end is nigh" hobo to warn humans about the upcoming Ragnarok (aka apocalypse). Looks like that rumor checks out now! Thor: Ragnarok opens November 3, 2017.
