The t-shirt seen on Drake appears to be a tribute to Frank Stacks and L-Money, who have been making music together as the Rap Is a Joke duo for over a decade. Social media accounts linked to Rap Is a Joke indicate that the operation, which produced the t-shirt Drake wore in the photo, is located in the Oakland area. Alongside their work in battle rap, the Rap Is a Joke Instagram page features music with a comedic twist, as well as a recent post showing Tech N9ne sporting the same t-shirt design. It seems that the t-shirt is a playful nod to the music and humor of the Rap Is a Joke duo.
