Kings Of Leon hire 'It's Always Sunny In Philadelphia" cast members Glen Howerton, Charlie Day, and the incomparable Danny DeVito for the promotional video for their upcoming album 'Mechanical Bull'. Well, they hire Glen to use Charlie's money to make the video. There is a close up of Danny DeVito eating a sub..or..a hoagie. There are also Ninjas and several meltdowns. Actually, I didn't see Kings Of Leon in this video at all...or hear their music. Wait..what was this for again?
