Here's why:
* Lead singer bald and wearing a faded Mickey Mouse t-shirt: Billie Joe Armstrong, the lead singer of Green Day, is indeed bald in the video and wears a faded Mickey Mouse t-shirt.
* Set in a shopping mall: The video takes place primarily inside a deserted shopping mall, with scenes of the band performing amongst the empty shops and escalators.
