A Field Guide to Office Workers

From the Joy of Tech, it's a Field Guide of Office Workers:

The Arrival Checker: Usually sighted twenty minutes before the official starting time. Feeds on the worried looks of co-workers faces. Considered a pest by everyone - except the boss.

Eyes Open Sleeper: Not as rare as they would seem. Long winded meetings and PowerPoint presentations are their natural habitat. Often this person calls out "Yes Sir" if startled.

Blackberry Addict: Easily identified by its tell-tale posture, shoulders hunched, fingers typing. Difficulty with awareness actually makes them prey for the office prankster.

Smoke breakers: Found outside in small groups regardless of weather. Any outward display of coolness is nullified by short life span and their smoky odor.

Too Tight Tie Guy: This guy has bizarre, suicidal dress habits. Could be storing fat for downsizing, or perhaps exhibiting a subconscious desire to asphyxiate himself in order to escape captivity.

Brooding IT Guy: Meek exterior can idea quiet, seething rage. Knows more about you and your computer habits than you do. Treat him with respect and assign in mundane work at your own peril.

The Strip Club for Lunch Guy: Loud and overbearing, they sometimes travel in packs. Often seen leering at office females. Scientists are mystified over why they are not yet extinct.

The Office Supply Pincher: Driven by bitter instincts and feelings they aren't paid enough, they hunt and gather office supplies and hide them in desks, or take them back to their nests
