I dislike people asking a question who have a preconceived answer in their head and are willing to then argue with you when your answer doesn't match their preconception.

Those who kick holes in lifeboats hoping to get a better seat.

People who use a hammer to drive in a *****.

Newbies who try to cross the street without looking at the light and the street signs saying "WRONG WAY".

Newbies who blame the dog cause the cat got pregnant.

Blame the developer because he made money off his/her ingenuity. Blame the Program because your system is not correct and cannot run it. Blame the Boss because the coffee machine ripped you off. Blame the keyboard because it misspells a lot of words.
