Women as Explained by Engineers

I've received an e-mail from a friend about 2 minutes ago and it contains pictures which I find funny. These things may have been posted on the internet a long long time ago, but I've only recently seen them, and since I find them entertaining, I've thought of posting them here.

Note: I don't bear any grudge whatsoever against Women/Girls (I'm a girl... but I the pics are really amusing). I also don't have any ill feelings/emotions towards engineers.

Deriving the Equation

So, how was it? haha gomen... btw, no story updates for the moment :( Maybe another time, ne?
