No matter how many flourishes and gadgets the Flying Karamazov Brothers add to their repertoire, no one will ever mistake them for Blue Man Group–a blessing for those who prefer their clowning analog rather than digital. The Brothers’ latest offering in their 30-plus years of juggling with jokes is Life: A Guide for the Perplexed, which takes its title and loose inspiration from 12th-century philosopher Moses Maimonides’s book of the same name. The show revolves around Paul Magid (aka Dmitri Karamazov), who’s undergoing a midlife crisis that somehow involves Bollywood musicals, Jacques’s “seven ages of man” speech from As You Like It, and of course the ever popular Karamazov challenge, “The Gamble”: audience members are invited to bring items onstage for juggling (featured objects have included skateboards and lubricated kelp). The Juggletron does give the show a Blue Man-esque touch: it’s a seven-foot-wide electronic instrument featuring MIDI drum pads. But what really keeps the Brothers flying high are their jokes–usually good-natured groaners–and astounding feats of hand-eye coordination. 11/26-11/28: Fri-Sat 8 PM, Sun 3 PM. North Shore Center for the Performing Arts, 9501 Skokie Blvd., Skokie, 847-673-6300. $42-$44.
