Transcript
Main comic:
A professor stands at a green chalkboard, back to the viewer, holding a piece of chalk and gesturing toward the board.
Professor (speech bubble): NOW, WE CAN GO DIRECTLY FROM EQUATION 4 TO EQUATION 19, THANKS TO THE "MATH PROFESSOR'S LEMMA", DENOTED AS "ℓ"
On the chalkboard, several lines of dense vector-calculus equations are written (integrals over volumes and surfaces with gradient, divergence, and dot-product terms).
Below the main equations, set off on its own, the lemma is written:
ℓ: fuck all y'all
Votey:
A hand-drawn box containing a formal mathematical restatement of the lemma:
∀x ∈ y'all
fuck(x)

Main comic: A math professor stands with their back to us at a green chalkboard covered in dense vector-calculus integral equations, holding chalk and gesturing. A speech bubble says: "Now, we can go directly from Equation 4 to Equation 19, thanks to the 'Math Professor's Lemma', denoted as 'ℓ'." Written on the board, separate from the real math, the lemma reads: "ℓ: fuck all y'all." Votey: A small hand-drawn box restates the lemma in formal logic notation: "For all x in y'all, fuck(x)" — written as ∀x ∈ y'all, fuck(x).
