It could be worse.

A truly pathalogical function. Continuous everywhere and differentiable nowhere.

A nice quote:

While it's not very common that badly-behaved functions arise in physics, there are functions which at least don't always remember to say please and thank you. They have to be gently corrected, but they're good at heart. The mathematicians are the ones who have to deal with the truly shady functions, the ones who form prison gangs and don't play by the rules and obey the laws. Or theorems.

I have an image of rogue mathematical symbols ganging up on me now. Great.
