Brilliant pranksters in Beirut, Lebanon, cause hilarity and mind-boggling bafflement with a prank in which they flash-mob people with cheering crowds holding up signs with the prank victim's face on.

For the prank, they take pictures of random pedestrians on the streets of Beirut and quickly blow up and print that photo onto placards.

Then, out of nowhere, a tour bus full of actors carrying those signs pulls up alongside the person in the picture, and cheers them on.

The subject is then totally baffled as to what is going on, to the hilarity of those around them.
