Avenue Q sends up popular children's television shows such as "Sesame Street" and "The Electric Company," while serving up a bounty of pop culture references and solving the mystery of the whereabouts of former "Diff'rent Strokes" child star Gary Coleman. The production bears the warning: "Full puppet nudity, not suitable for children."

The show's creators Robert Lopez and Jeff Marx earned a Tony for their score as did bookwriter Jeff Whitty and the musical itself garnered the top Best Musical prize at the 2004 Tony Awards.

Avenue Q recently presented a Times Square-set presidential debate — complete with felt-skinned versions of Bush and Kerry, balloons, red-white-and-blue ribbons and, of course, singing. (To view photos, click here.)

Avenue Q plays at the Golden Theatre, 252 West 45 Street. For more information on the show and event, visit www.avenueq.com.
