The only reason they didn't bring Pimp C out is because he's been dead for over 10 years, and I'm not sure what conditions his remains are in. If he wasn't cremated, they'd have to prop him up and wheel him out on a dolly.
If he was cremated, Peter Rosenberg could scatter his ashes to the wind and let them blow back in his face, like Donny in the Big Lebowski. Or do they still have him out in the parking lot introducing rappers no one ever heard of? That's what they had him doing years ago, and his profile has only decreased since then. He's been demoted to Ebro's sidekick, and it doesn't make sense for a half white guy to have a white sidekick. A similarly useless black guy would have been kicked to the curb years ago.
But I digress.
Anyway, Hot 97 had someone who doesn't know from rap music—another white guy, possibly someone's nephew—running their social media. Some singer I'm not familiar with (perhaps SZA, or Sia) brought Bun B out to perform "Big Pimpin," and the kid running the Hot 97 Twitter must have shazamed the song and determined that Pimp C was there on the stage, not unlike when the founders of Rap Genius thought Dallas Penn was Smoke DZA.
Also, there was a controversy involving 6ix9ine not being allowed to enter the venue. Ebro had him banned, because I guess they had some sort of disagreement? 6ix9ine showed up anyway, in a disguise, and Ebro, who's been known to call the police on people (e.g. Star, Taxstone), sicced the police on him. Fortunately, 6ix9ine didn't get arrested. Lord knows he's got enough problems.
