that entrance never really made sense to me
i mean it was cool and all but why the machineguns? afaik his character never had anything to do with guns or weapons of any kind, he was just a big dude that did power moves. also the grenade toss always felt unnecessary, sometimes he did it in a way that looked intense and badass, sometimes it sucked (like in OPs webm).
i mean it's far from the worst one ever and Dave + the music made it iconic but still it could be improved
