Music video
The music video for the song predominantly shows geriatric people dressed and acting like young people. The various members of the band are shown interacting with the older characters (for example playing video games and giving massages). At the end of the video, Benji Madden wakes up to find an old woman wearing one of his shirts and offering him a bowl of cereal.
The video for "Girls & Boys" was shot in the suburb of Ellerslie in Auckland, New Zealand. The longer version includes dialogue of a senior woman and the band, a parodying reference to Avril Lavigne's video "Complicated".
