"Alpha Dog" is the lead single off of Fall Out Boy's greatest hits package Believers Never Die (which dropped yesterday). And, in sticking with the retrospective theme of the compilation, director Harvey White uses the "Alpha Dog" clip as an opportunity to do the remembrance-of-music-videos-past thing.
It all kicks off with a faux-disclaimer from Pete Wentz, warning viewers not to try any of the acts they are about to see performed in the video. This is bad news for any prospective FOB cover bands, one would assume.
The rest of it is a blinding montage of shots and scenes from previously released music videos, as well as some candid stuff featuring pranks, pratfalls and grown men getting hit in the crotch by baseballs.
