A standout in stand-up on Comedy Central

The funny business at Comedy Central comes in all shapes and sizes, from the spoofery of the new “Reno 911!” series to the warped wit of “South Park,” from the news-skewing of Jon Stewart’s “Daily Show” to the frat-boy bluster on “The Man Show.”

But for seven seasons now, “Comedy Central Presents” has dispensed with all the setups and extraneous trappings and distilled the humor product down to its purest form, the stand-up stage.

There, it’s all about material, presence and delivery, and tonight at 10, comedian Tracy Smith scores well in all three categories.

The 34-year-old native of northern Ontario, Canada, has been bouncing around the fringes of fame for the better part of a decade, plying her edgy, sweet-and-sour takes on relationships and pop culture in clubs and across the dial: MTV (“Half-Hour Comedy Hour”), Lifetime (“Girls Night Out”), A&E; (“Evening at the Improv”), NBC (“Late Fridays”), HBO (“Best of the Fest”) and Comedy Central’s own “Premium Blend” and “Make Me Laugh.”

The steady work has paid off.

Smith’s aging-single rants are as tight as her skirt as she boasts of “going through men like Kleenex” while in her 20s, only to lament her preening pickiness a few years later.

“Where’s the one who liked me too much?” she says, searching through an imaginary heap of balled-up tissues. “Where’s the one who was too nice?”

Working in front of a set that resembles a Bedouin boudoir, complete with hookah, the blond and buxom Smith hits the mark most often when she sticks to the dating scene and dealing with getting older (“Women over 35 are beautiful,” she says. “Especially the ones who look really young.”)

Observations on shopping seem a trifle toothless by comparison (on her weakness for Target sales: “I bought patio furniture. I don’t even have a yard”), but Smith works the material so nimbly that you’ll scarcely notice. Surely her own sitcom can’t be far off.
