No matter how much you want them, some things are just not meant to be: fire and water, good and evil, or roots and negative numbers. There is no real number that can be squared to get -1, but, for some mathematical operations, you need to do exactly this (did somebody say fractals?). To address this problem, complex numbers were introduced. If it doesn't fit, use a bigger hammer. Or, invent a hammer that will do the job. Good job, maths!
With this mug, you can not only show your undivided (badum-tss) love for mathematics on the go, you can also use the opportunity to tell people everything you like about maths while explaining the joke. Because, let's be honest for a second: maths is more exciting than most people would think. You just have to help them realise it ;).
