"Today, I get to share with you the visual companion piece to my new single, 'Grenade.' The song is about loving someone so deeply, and the pain of knowing that the person you love does not feel the same. The actions in this video serve as a metaphor, and should not be taken literally. I am aware of the power of visual media, and I encourage everyone who watches this video to understand that it is an artistic interpretation of the song, and not something to imitate." -- Bruno Mars
The ending of this video shows him killing himself. That.s why Bruno Mars himself advises his viewers not to imitate the action - but to understand the meaning behind it.
Ah. Why don.t you catch a grenade for me? I promise I.ll do the same for ya :)
