This episode parodies the real life fact that Hulu pulled both "Lethal Weapon" episodes due to insensitive instances of blackface.
This episode features many callbacks to previous characters and situations, one being Pepper Jack, who debuted in S3 E10, as did Dennis' Fraggle Rock thermos.
When Dennis is speaking with "Don Cheadle" at the end, he goes through all the character's previous names (Donovan McNabb, Tiger Woods) he also refers to him as "Elvin" - the character he played in The Cosby Show.
