Recently in San Francisco, a man walked around in a suit. But it wasn’t really a suit. It was a pullover onesie that just happened to look like a suit.

The “Suitsy” is now on sale from a Bay Area retailer for almost $400, which may come as a surprise to Andy Stuckey and Jon Murray. In 2008, the musical comedy duo — appropriately named Stuckey and Murray — invented the “Fuxedo,” which is basically Suitsy in a less-practical-for-daily-use tuxedo form. It might be time for them to call a lawyer.

When they’re not dealing with potential plagiarism claims, Stuckey and Murray have been pretty busy in the comedy world since joining forces a decade ago. Armed with acoustic guitars, the pair has appeared on shows like Last Comic Standing and at international festivals like Edinburgh Fringe, attracting audiences with sketches and songs like “Mimosas in the Rain” and “Taking a Dump at Work.” With four albums under their belts, plus jobs producing, writing, and directing for MTV2’s Guy Code, Stuckey and Murray have definitely come a long way since they first met as NBC pages back in the early 2000s.

“You’d think after having a combined five kids between us we’d be a little more refined,” they say. “But we’re still cranking out songs about sampler platters and when the most appropriate time to have sex with your wife is.”

The act recently added a third member, John Foti, an accordion/piano/saxophone player who can relate to all of their dad jokes. And over the years, they’ve come up with a pretty clever strategy for testing out material: If their wives don’t like it, their fans certainly will.

“All an idea has to do is make us laugh. That’s our barometer,” they say. “Unless, of course, he’s laughing for the wrong reason. Then we burn it and no one ever speaks of it again.”

Fortunately, the guys are pretty flexible, so those ideas can turn into sketches or full-fledged musical numbers. “If there’s a lot of back and forth to push the scene further, chances are it’ll be a sketch,” they say. “But sometimes a melody pops into your head and before you know it, you’re trying to come up with a rhyme for how sexy a grandmother is.”

Some of their funniest bits have made their way to YouTube, where videos like “Awkward Sex” and “Auto Phone Sex” (not related) have amassed millions of views. You can expect just as many laughs from the live show.

“Sometimes there’s choreography. Sometimes we do multimedia shows. One of us might fall in love with a girl in the front of the house,” they say. “We may just play Chumbawumba’s ‘Tubthumping’ 14 times in a row. Who knows?”
