Rolle Memes

The mathematical pun that launched a thousand groans! "Rick Rolle's Theorem" brilliantly transforms the serious Mean Value Theorem from calculus into an unexpected rickroll. The graph shows a continuous function with the classic bell curve that, according to the theorem, must have a point where the derivative equals the average rate of change—but the "rolle" part is actually a fountain pen nib! It's the perfect marriage of mathematical rigor and internet trolling. Professors worldwide are simultaneously impressed and disappointed in themselves for understanding this.
