It was a lame attempt at robbing a bank - so lame that even the bank employee began to laugh at the robber's "brazen" heist.
The incident happened in Shanghai, China, last week, the Mail Online reported.
The woman teller at a China Construction Bank branch has since become an online sensation after she was caught on camera laughing at the armed robber.
Surveillance footage shows the would-be bandit, dressed in a blue jacket, calmly approaching the teller while she is helping a customer.
The man holds up a 17cmlong meat cleaver to the glass between him and the teller, and keeps it there while talking on his mobile phone, the New York Daily News reported.
Confused, the bank teller looks to her colleague on her right even as her customer picks up her bag and calmly walks away.
Video footage then captures the teller turning around with a smile on her face and her thumb pointing towards the robber, as if it is a joke.
Meanwhile, security guards approach the man, who is believed to be mentally ill. They easily pin him to the ground.
The video was uploaded to LiveLeak, a video sharing website. It has since been viewed about 50,000 times.
