Sarcastic Remarks For Work

And your crybaby whinny opinion would be...?
This isn't an office. It's Hell with fluorescent lighting.
I started out with nothing & still have most of it left.
I pretend to work. They pretend to pay me. Sarcasm is just one more service we offer.
If I throw a stick, will you leave?
If I want to hear the pitter patter of little feet, I'll put shoes on my cats.
Does your train of thought have a caboose?
Errors have been made. Others will be blamed.
A PBS mind in an MTV world.
Whatever kind of look you were going for, you missed.
Suburbia: where they tear out the trees & then name streets after them.
Well, this day was a total waste of makeup.
See no evil, hear no evil, date no evil.
Not all men are annoying. Some are dead.
A woman's favorite position is CEO.
I'm trying to imagine you with a personality.
A cubicle is just a padded cell without a door.
Stress is when you wake up screaming & you realize you haven't fallen asleep yet.
Can I trade this job for what's behind door number 1?
I thought I wanted a career, turns out I just wanted paychecks.
Too many freaks, not enough circuses.
Macho Law prohibits me from admitting I'm wrong.
Nice perfume. Must you marinate in it?
Chaos, panic, & disorder - my work here is done.
I plead contemporary insanity.
How do I set a laser printer to stun?
Meandering to a different drummer.
I majored in liberal arts. Will that be for here or to go?

Adolphe Quetelet

Died 17 Feb 1874 at age 77 (born 22 Feb 1796). Lambert-Adolphe-Jacques Quetelet was a Belgian astronomer, statistician, mathematician and sociologist whose career began teaching mathematics at the Athenaeum, Brussels (1820), while also pursuing the study of astronomy from 1823. Quetelet was instrumental in setting up, and became the director of, a newly equipped Brussels Royal Observatory (opened 1833). From 1825, he began writing papers on social statistics, and in 1835 gained international recognition for publication of Sur l'homme et le developpement de ses facultés, essai d'une physique sociale. Whereas the normal curve had previously been applied to error correction, Quetelet used it to illustrate a distribution of measured human traits about the central value, giving the concept of the average man at the peak. In this way, for example, he applied a statistical view to the nature of criminal behaviour in society.«Image: from a 1974 Belgian postage stamp.
