**You are a nerd if you know that the batman function is:**

"1.5*sqrt((‑abs(abs(x) - 1)) * abs(3 - abs(x))/((abs(x) - 1)*(3 - abs(x)))) * (1+abs(abs(x) - 3)/(abs(x)- 3)) * sqrt(1 - (x/7)^2)+(4.5+0.75 * (abs(x - 0.5)+abs(x+0.5)) - 2.75 * (abs(x-0.75)+abs(x+0.75))) * (1+abs(1 - abs(x))/(1 - abs(x))), (‑3)*sqrt(1 -(x/7)^2) * sqrt(abs(abs(x) - 4)/(abs(x)-4)), abs(x/2) - 0.0913722 * x^2-3+sqrt(1 - (abs(abs(x) - 2) - 1)^2), (2.71052+1.5 - 0.5 * abs(x) - 1.35526 * sqrt(4 - (abs(x) - 1)^2)) * sqrt(abs(abs(x) - 1)/(abs(x) - 1))"

Crazy. No tax in Canada on "real" books but ebooks get slapped with them. In the UK, same thing -- tax is 20% on ebooks, nothing on print ones. Same thing also in Norway and Denmark, apparently. Via +Gary Price
