Tough-looking with their cockscomb mohawks — the red one topping Ketch!; the yellow one, HIRO-PON — the "silent-comedy" duo Gamarjobat ("Hello" in Georgian) are now well into a 31-stop tour that's filling theaters around the country with whoops and rollicking laughter — as well as their own "language" of grunts, baby noises and crazy exclamations.

Coming hot on the heels of 2010's sell-out nationwide tour, this year's show again includes a set of hilarious routines that sometimes flirt with the bawdy, followed by a narrative piece. This time, however, the pair are performing their first new story line for five years — a sci-fi mime drama.

Innovation, though, has been a constant since pantomime artist Ketch! and theater performer HIRO-PON met in 1995 and, realizing they shared the same sense of humor, formed Gamarjobat in 1999.
