Brain (Lil Dicky)

Brain is a comedic alter ego created by American rapper Lil Dicky (David Burd), first introduced on the 2015 song «Pillow Talking» and later given a distinct physical form — an animated, exposed pink cranium — through CGI in the song's 2017 music video. Conceived as the literal embodiment of Lil Dicky's mind, Brain is portrayed as the source of his rhymes, wit, and creative instincts, appearing as a separate character who argues with, advises, and occasionally overrides his host.

The character sits within Lil Dicky's broader comedic-rap persona, which blends absurdist humor with genuine technical skill on the mic. Songs credited to Brain extend this bit, framing him as an independent artist with his own catalogue and creative voice, distinct from but tied to Lil Dicky's main body of work.

Brain became one of the more memorable visual gags in modern comedy rap, contributing to Lil Dicky's reputation for blending high-concept sketch humor with earnest musicianship. The character has been discussed in interviews as a way of externalizing the creative process itself, turning songwriting into a kind of internal dialogue made literal on screen.
