Because this makes sense.
Illinois-born rapper Common (aka Lonnie Lynn) and McLovin from "Superbad" (who you probably don't know as Christopher Mintz-Plasse), have teamed up in an online-only remake of the 2001 hit "Training Day" (NSFW -- language).
And McLovin is Alonzo.
The five-minute vid's short on verite and long on spoof but, like the movie, shows McLovin/Alonzo forcing Common/Jake to smoke PCP. As with the original film, Alonzo then drops Jake off with a trio of card-playing eses. Jake, despite stumbling through a drug-induced fugue, escapes, confronts Alonzo, and shoots him in the ass.
