Well, we all know that the best people at writing code happen to be ninjas (have you read any job descriptions or got any recruiter emails lately?), so I think this may perhaps be the reason.
Still open to explanations of why ninjas have an enhanced coding ability though.
I also heard that they can see in the dark thus you can cut the light when you leave them in the office.
On the other hand, I've seen it in the movies that they can disappear... I assume that's what they do before someone can actually try to run their code.
