Attention bank robbers, perhaps you should complete your phone call before shouting "stick 'em up." A deranged knife-wielding bank robber walked into China Construction Bank in Shanghai and while still on the phone, attempted to rob the bank. Things did not go as he planned.

The man entered the bank and, at first, it looked like he was just going to pull the fire alarm. He then approached the counter with a clever, a guard noticed this, and then supposedly shouted at him. After he pulled out the giant knife, he allegedly told the teller, "This is a robbery."

The rest is hilarious as he is just laughed at, and then tackled to the ground.
