So, I got this new coworker of mine, he's 5 years older than me and says he's got a loooot of experience with html, css und javascript. Nice. Boss wants us to blur some text on a website, I show him how to do it with css "filter: blur(4px)".

5 minutes later he's all proud and says "done". I think nice, check the code - and see this moron having put an <img> png in there, having blurred the text with photoshop. Short memory, anyone?
