One is most likely recognizable for sitting in the driver’s seat at a Sonic Drive-In. The other was told to “shut up” by Tina Fey so many times over the run of the sitcom “30 Rock” that it became his Instagram handle. Together, Peter Grosz (“Veep,” “Wait Wait … Don’t Tell Me!” and those “two guys” fast food commercials) and John Lutz (“Mapleworth Murders,” “Late Night with Seth Meyers”) are two of the most talented improvisers working. Their long-form collaborative show “2 Square” – the more compact, traveling version of the long-running “4 Square,” which they’ve performed going back more than a decade in Chicago with Rob Janas and Dan Bakkedahl – is character-rich, absurd, self-referential and yet ties itself up neatly by the end of its 45-minute runtime. As is the nature of improv, I can’t tell you much more about the show than that; frankly, neither can they, but that’s the point.
“John Lutz and Peter Grosz: 2 Square” at 9 p.m. Oct. 21 at The Rockwell, 255 Elm St., Davis Square, Somerville. $22 to $27.
