1. Arnold Schwarzenegger
Finally we arrive at the top spot, and the idea that spurned this article; old gettin'-crustier-by-the-day Schwarzenegger. Incase you're not up to date with the latest happenings in the viral video world, Arnold recently took to a Californian gym to encourage those inside about how best to work out. How did he do such a thing without having an instant fan-furore materialise out of the ground you ask? He donned a bleedin' great moustache and a long-haired wig, complete with ponytail of course. Whilst the video itself starts out by showing one of the people who did actually clock it was him, I must say how does everyone on Earth not instantly recognise that voice?? He could be approaching you from a neighbouring alleyway, and emit nothing more than a few barely audible grunts and you'd know it was Arnie. Then again, would you actually want to address the person right in front of you as 'Ah-nuld', even if you were convinced it was him? Chances are the denizens of this fine gym thought he'd gone off the deep end, and were trying to avoid getting pulverised before teatime. So there you go, perhaps you've had some bizarre encounters yourself you'd like to share? Or any other famous tales of icons-gone-incognito? Let us know in the comments!
