Assassin's Creed 2: England

If you've played Assassin's Creed, this is one of the funniest parodies out there...if not, well...you'll get the picture. One thing - in the game, you 'blend' into a crowd by walking like the monks whose cassocks look conveniently like Assassin's robes...and you can escape the attentions of pursuers if you get out of sight for a moment and then nonchalantly sit on a bench between people.
This of course would not go down very well at an English car boot sale.

"He's creepin me ooooouuuut."

I appreciate that this might look like bad humorous cosplay inflicted on nice people having a quiet day out, but trust me THIS IS FUNNY.
