For once (and presumably the only time), calculus is funny:

Question: Rafael tries to find f`(2) where f(x)=x^5. He substitutes 2 for x and gets f(2)=32. Then he differentiates 32 and gets zero. Explain why he also gets a mark of 0.

Answer, as scribbled in pen in the margin by someone who is not Kali: CAUSE HIS NAME IS RAF.

Oh, the hilarity.

Omfg.
