The mother of all pranks is here. It started with a fake Barack Obama (a lookalike, if you please), fake security entourage, and a handful of fake fans and slowly brought the usually jam-packed New York City Times Square to a stand-still with thousands of Obama fans waiting for a glimpse of POTUS.Made by the YouTube channel, ModelPrankstersTV, the prank was clearly a hit as it managed to fool almost everyone who wasn't in the know and present in Times Square at the time. What this prank also effectively portrays is that it just takes a rumour to get a fire started.Once word had spread that 'President Obama' was in the vicinity, it only took a few minutes for the tourists to follow 'him and his entourage' around, filming and taking pictures of what they thought was a walk with the President of the United States of America!Watch how these pranksters brought NYC Times Square to a stand-still, and why they had to cut the prank short:
