Featuring people with fish tanks on their heads, the music video was directed by Travis Kopach and filmed on June 19th, 2006 in Los Angeles. It premiered on MTV on July 14th 2006. The band felt that their looks were distracting from their music, so it only shows them in a single scene (they are the paramedics).
One popular interpretation is that the man (Daniel Gomez) and the woman (Molly D'Amour) are married, and the husband knows his wife has been unfaithful, thus feeling unloved. The woman, at one point, picks up a goldfish and places it in her fish tank, which represents her sleeping with another man. The depressed husband commits suicide.
According to those who believe this interpretation, the number of fish in a tank symbolize the amount of people a person has slept with, leading to the conclusion that the wife, who has a number of fish in her tank, has been promiscuous outside her marriage and her husband has only one clearly visible fish. However, upon closer inspection, there are numerous fish in his tank, though only one of them is a bright orange and easily visible. The orange fish signifies his faithfulness to his wife, and the harder to see fish represent past and forgotten lovers.
Panic! At The Disco has stated that the music video is simply a 50's period short film, and that the husband and wife are a couple but not necessarily married.
