DON'T BE A JERK!

Today, while sitting in my physics class, I saw a very funny shirt that one of my peers was wearing. You need some knowledge of physics and calculus to understand this one. Take a look below.

Still don't get it? You need to know that s is displacement. The derivative of s with respect to time, (d^2)s/(dt^2), is acceleration. The derivative of acceleration, (d^3)s/(dt^3), is called jerk. So the shirt read "DON'T BE A JERK."

Pretty funny, right?
