Nice to see how funny pictures can trigger serious arguments. I just laughed when I saw the picture, thinking "how true! :'D"

Kinda offtopic, but it reminds me of a programmer who said "if you use Photoshop and don't understand what the filter actually does, you're a noob", then explained what Filter XY does and tried reproduce the effect using the basic methods behind the filter. Didn't see the outcome, but he used such a complicated way that I was just thinking "Wtf? Okey.... if you like to do it this way, go on" (...and waste more time!). [/offtopic]
