I don't know. It's a picture of some guy! That's proof right there! I doubt there are any random people out there who would take part in such a ruse.
I googled Jack Handey a few years ago. There was nothing about him except his "deep thoughts" page. True story. He's done all this stuff for all these years and there was nothing about him out there. Sure, I know it DOES take a while for the interwebz to catch up to stuff...usually 8-10 years before we even hear of it. Information on the information superhighway is pretty slow.
Anyway, it's just a little theory I like to entertain. I'm not interested into getting into a whole dissection of every picture and article and cite y'all post. They're all fishy to me.
I hope this is one of those things that one day, it's found out to be true, just so I can be the only person on earth to say "I told you so."
Until then, I won't be swayed by the stuff you guys post from the interwebz that has to be true because you found it on the interwebz.
