Everyone was crowding around, trying to get an autograph or snap a picture. After all, it is not every day that you get to see a real Korean celebrity in the flesh.
Except, no one knew who the celebrity actually was.
This "celebrity" was not a famous actor or musician. He was actually online personality George, who was filming a prank video produced by YouTube channel Re-Productions TV to see how the public would react to a completely unknown person posing as a celebrity.
Dressed up like a Korean star with his suave hairdo and an oversized black t-shirt, George got other actors to play various members of his entourage, which included his wife, a personal assistant, and two bodyguards to flank him.
Wearing dark glasses and armed with a selfie stick, he begun strolling through the mall in Weifang, China. It didn't take long for people in the mall to start following him around, taking photos and asking for autographs.
The cameramen also took the opportunity to interview "fans" to ask if they liked his movies. Some thought that he was in the Fast and Furious 7 movie, while others just claimed to like all of his works.
One enthusiastic girl even asked the interviewer to "say hi to oppa (Korean for brother) for us".
The video quickly went viral, with over 2.6 million views since it was uploaded last month.
This prank is perhaps the opposite of the one pulled by record-busting singer Adele, who pretended to be an Adele impersonator to fool other Adele impersonators.
Here in Singapore, YouTuber Jonathan Lee played a prank at this year's Laneway Festival, where he got concert-goers who wanted to look 'hip' to express appreciation for entirely made-up bands like 'Forrest Gump' and the 'Phua Chu Kangs'.
