For the past few weeks, On The Job has been obsessed with the impact of cable television’s hit shows such as “Queer Eye for the Straight Guy” and “Sex And the City” have on our behavior, values, and vocabulary at work.

For working New Yorkers, though, no single show rivals HBO’s “The Sopranos” for sheer volume of material you can use at work. In New York, for one thing, you can use Sopranoisms and avoid sounding as strangely out-of-place as you would if you were in, say, Kansas City. For another, many of us work with characters who act, sound, and probably smell like Tony Soprano’s Essex County, N.J.-based tribe. That makes us different from people who work in Tacoma, Wash.

“The Sopranos,” against all odds, has stayed remarkably trendy through five seasons on HBO.

The television trend-monitoring Web site JumpTheShark.com confirms the show has never “jumped the shark,” a phrase derived from the worst-ever television show episode, when Fonzie of the ’70s classic “Happy Days” was pretending to water ski and hopped over one of the killer fish’s dorsal fins. When a show “jumps the shark,” it seems, it skips into cultural irrelevance. The HBO series’ remarkable endurance means that we still see Sopranos T-shirts and jackets on casual Fridays. It also means that nobody has yet been shamed into peeling those Bada Bing! bumper stickers off their Honda Civic. Because the show is still cool, people at work continue to behave like Sopranos.

On The Job’s raison d’etre is to give you lessons, language, and laughs you can use at work, today. After deep dredging, I found the show’s seven most important contributions to today’s work culture.

Hopefully, some of these gems have yet to hit your windshield as you retrace Tony Soprano’s ride in the opening credits, featuring the New Jersey Turnpike, the Lincoln Tunnel, the Pulaski Skyway, Wilson’s Carpet Giant in Jersey City, Satriale’s Pork Store in Kearny, and Pizzaland in North Arlington.

Soprano On The Job Contribution No. 7: Emotion is bad for business.

When Tony Soprano first appeared in 1999, he endeared himself by being America’s first mobster to have so many problems that he needed a psychiatrist and Prozac. Managers could relate to his employee problems. Employees could see aspects of their boss’s bad behavior in Tony’s whim of steel, his radical mood swings, and irrational decisions. And then when Soprano uttered the immortal words “Those feelings are starting to bleed into my business,” we all knew what he was saying. And we still do, especially when we’re comforting some blubbering teary-eyed co-worker while simultaneously fretting about that upcoming deadline.

Contribution No. 6: Proliferation of Soprano humor.

David Letterman’s Top 10 List gave us the two best reasons to love laughing at “The Sopranos” at work: “You don’t need to worry about one of them asking to go home early for Rosh Hoshana,” and “working for Tony means that in addition to disposing of bodies, you’ll have to learn to use PowerPoint and Excel.”

Contribution No. 5: What to say to a rival co-worker when he or she gives you the evil eye. “You’re lookin’ at me like you’re thinkin’ I clipped your uncle.”

Contribution No. 4: What to say just before you criticize the boss’s most recent stupid idea. “All due respect…”

Contribution No. 3: Greeting people like a Soprano. “What is it you wanna say to me?”

Contribution No. 2: Common descriptions of at-work behavior straight out of the mob dictionary. If someone comes to a meeting with lots of materials, she has “come heavy,” Soprano-speak for wearing a gun.

When someone is overly greedy, Tony would say he or she is “eating alone.”

Paying a commission or a referral fee is now “paying tribute,” just like Tony’s regular deliveries of bags of cash to Uncle Junior.

An invitation to lunch is now “wanna go get gabagool?” a quote straight from overweight Soprano soldier Bobby “Bacala” Baccilieri, played by actor Steve Schirripa.

A thousand dollars is no longer “a grand,” it is “1 large.”

And a broker’s commission is now “Vig,” Soprano-ese for vigorish, or a bookmaker’s cut of gambling action.

Contribution No. 1: Phrases that let you end a meeting (or a newspaper column) just like a Soprano. “So, we are probably done here, right?” “Toodle-bleeping-you.”
