Phaahhh

A clown in a colorful costume stands on an escalator, then suddenly lunges forward and grabs a woman in a black shirt, causing her to stumble and fall backward onto the descending escalator steps. The woman, startled, clutches her bag and falls down the escalator as the clown remains at the top, then bends over. The scene takes place in a shopping mall with multiple escalators and other people visible in the background.
