So you think you’re funny, do you?

Ever wanted to try your hand at stand-up? One Boston comedyshowcase is calling your bluff.

Stand Up Break In,produced by Boston comics and hosts Danielle Andruskiwec and David Thomas, combines seasoned local comics, a headliner and two straight-up first timers — or at least relative rookies — together on-stage at The Riot Theater in Jamaica Plain.

The structure is aimed not only at encouraging tepid newbiesto try stand-up in a bona fide comedy club with other comedians, but attracting supportive audiences who root for the underdog, Thomas said.

“At a lot of open mics, you don’t have an engaged listeningaudience,” hesaid. “There’s no substitute in having to do open mics every week, [but] if we can just have [first-time comics] do one show and give them that confidence boost, that’s really what we’re trying to do.”

Judging from past participants, Andruskiwec and Thomasmay be onto something. Kiritan Scott Stewart, 21, of Manchester, New Hampshire, was a lifelong comedy fan who first toyed with the idea of trying stand-up in his teens. After a friend told him about the show, he was sold on its premise and decidedto give it a shot.

Despite feeling “tremendously nervous” before he got onstage, Stewartsaidhe quickly found his rhythm.

“As soon as I started to feel the laughs and got intothe bit, I definitely calmed down and felt comfortable,” hesaid. “I wasn’t expecting [it] to be so welcoming, and after, to have so many people congratulate me and tell me what a good job I did.”

Chris Kaufman, 36, of Somerville, agreed. He hadsome experience with improv comedy before his premiere at Stand-Up Break In, butwas always intimidated by the prospect of performing stand-up by himself. Now he’s a regular at open mics throughout the Boston area and came back to perform at the showin October.

“I’ve never seen a non-supportive audience in that space,”Kaufmansaid. “Many of the comedians that are there are well-respected in the Boston community, but they’re always clapping and cheering you on. It’s a pretty cool experience.”

Jess Salpietro, 26, Somerville, also an improv performer, shared Kaufman’s fear of performing alone, along with his surprise at how rewarding she found the experience.

“I have plans for 2016 to start doing more open mics andstart exploring that part of the comedy scene,” shesaid. “It definitely sparked some new ideas.”
