Jackie Flynn is only 50 years old, but you could say he’s an “old school” comic — he’s been out there on the comedy-club circuit for 26 years now.

So, it’s understandable that he takes a dim view of the current trend that he refers to as “YouTube comedy.”

“You know — like, when someone puts together five or 10 minutes worth of material, and they put up a You Tube video of themselves, and they’re suddenly a hot commodity, and people start following ‘em on Twitter, so a lot of the club owners or managers want to book them — because they’re temporarily famous. And, as a result, their club shows sell out,” says Flynn.

“And all of a sudden, club owners I’ve been working with for 20 years, now I can’t get ‘em on the phone — because they’re more interested in booking these Internet comics.”

But if a comic only has 10 minutes worth of material, a 45- to 60-minute club set can be grueling to sit through, observes Flynn, a Boston native who has lived in Los Angeles for about 15 years. “I honestly don’t know how they do it — they’ll do what little material they have, and they just have conversations with the audience for the rest of the set. To me, that’s not comedy.

“It used to be, of you were funny, and you worked hard, and didn’t steal other comics’ jokes, that’s the way you got bookings and had a career,” says Flynn, who comes to the Ann Arbor Comedy Showcase for a three-night stand, Thursday through Saturday. “But it seems like, all of a sudden, the rules have changed.”

But Flynn emphasizes that the Showcase is not one of the clubs who favor the newer “YouTube comics.”

“I’ve been working with (Showcase manager) Roger Feeny for a long time, and he definitely values and appreciates comics who’ve paid their dues and have put together a good, strong set of material.”

This phenomenon, though, is one of the reasons that, after 26 years of playing clubs, Flynn wouldn’t mind landing a TV sitcom gig. “Having a TV show is good on a couple of levels - the income is good, so you don’t have to do be on the road as much, so you you’re not up in Manitoba in January doing a show,” he cracks. “Plus it enhances your visibility.”

Flynn has already enjoyed some of the visibility-enhancing benefits of being onscreen. For a time, he had a recurring role on the “King of Queens” sitcom with Kevin James, and he’s a favorite choice of the Farrelly Brothers when they cast comic actors for supporting roles in their movies. He’s had smallish roles in several of the Farrellys’ films — “There’s Something About Mary,” “Kingpin,” “Me, Myself and Irene, “Shallow Hal” and “Stuck on You.” He’s also appeared in “Mall Cop,” with James, and he had a role in the latest Farrelly film, “Hall Pass” — but his scenes ended up being trimmed from the final cut.

“Ah, that happens sometimes,” shrugs Flynn. “But the Farrellys are great guys — they’re real, regular guys, they’re not Hollywood types, and they’re loyal.” Flynn also sometimes works with the Farrellys as a writer if a script “needs punching up,” says Flynn, who has his sights set on the role of Moe in the Farrellys’ upcoming “Three Stooges” movie.

“There might be some pressure to get a big-name celebrity comic actor” for all three of the principal roles — “but they might decide not to in that direction. So if they don’t, I’m in the hunt for the Moe part,” says Flynn, keeping his fingers crossed. “That would be a home run, career wise.”

In April, he’ll be shooting another film with James, “Here Comes the Boom,” and he’s also currently planning to film an upcoming gig, which would air on Comedy Central and also be sold on DVD.

As for his own material, Flynn’s work leans toward what you might call the “edgy / sarcastic / observational” approach — observing everyday foibles, and talking about things that “everyone is thinking, but they just don’t say it.” And he likes to riff on “things that I find ludicrous. You know, stuff that aggravates me” - which underscores the truism that, in order to be a comic, "you have to be easily annoyed," as Jerry Seinfeld once put it.

On his last comedy CD, “Irascible,” he caustically riffed on shopping clubs, the Department of Motor Vehicles, bathroom attendants, infomercials, Jerry Springer and terrorists and flying - and also had bits with titles like “F---leberry,” “New Orleans, Pedophiles and Such,” and “Yeast Infection, Sperm Bank, Gay Day” — so he would also definitely be classified in the “adult humor” category.

Like most working comics, he’s always working up new material, so he says that, for his Ann Arbor show, he’ll still be doing “maybe 15 minutes of the material on that CD, and the rest will be new stuff.”

Some of his favorite new bits plumb topics like religion, racism, the Jamie Lee Curtis TV ads for Activia yogurt — and new bits on infomercials.

“Yeah, infomercials are a good source of material,” says Flynn with a laugh. “Because, a most of them are pretty cheesy or annoying.”
