At approx. 1:03, Rock mentions that even in animation, Will Smith is bigger than he is. Since he was a zebra (in Madagascar) and Smith was a shark (in Shark Tale). But Smith's character was actually a bluestreak cleaner wrasse. Not a shark. In addition, a bluestreak cleaner wrasse normally only get to be about 10cm in length.
When Chris Rock is delivering a routine about Will Smith, at one point he accidentally mentions Emancipation (2022) (which he talks about later) instead of Concussion (2015). As the broadcast is live, he admits his mistake, saying: "No, not Emancipation; I fucked up the joke. Concussion."
