Take this quiz to see if you can tell which ones are Serial Killers, and which are Programming Language inventors...

I didn't do so well - got 5/10. Scary!
The other weird thing was that one of the people reminded me of one of my University lecturers, although he'd be closer to a programming language inventor than a serial killer, I think..., but maybe that's just bad judgement considering my score.... :|
