said Mildred, "... Fermat's Last Theorem is a method to find local maxima and minima of differentiable functions on open sets by showing that every local extremum of the function is a stationary point (the function derivative is zero in that point)."

Ted retorted "Hah, you daft trollop. I asked about Fermat's Last Theorem. You've confused Fermat's Theorem Regarding Stationary Points with  Fermat's Last Theorem which states that no three positive integers a, b, and c can satisfy the equation a^n + b^n = c^n for any integer value of n greater than two.

Meanwhile, Mildred's Mother was attempting to make the photographers head explode using only mental telepathy.
