A parody of the opening scene of that "This is America" video by Donald Glover/Childish Gambino. I haven't actually seen the video in its entirety yet. I keep hearing it's got tons of race-baiting propaganda in it but it does seem like rather amusing meme fuel so I figured this was worth it. :3
If Pinkie were doing it, she'd totally use the party canon instead of a real gun. XD
