There is laughter on two fronts this week: in Colorado, where a comedy festival is in the works, and in Baghdad, where Robin Williams is entertaining the troops.

First, out West: Drew Carey, Chris Rock, Louis C.K. and part of the gang from “Sex and the City” are confirmed to participate in Aspen’s 10th annual U.S. Comedy Arts Festival from March 3-7, reports Reuters.

Carey, 45, is due to host an end-of-festival evening show capping the fest’s first decade, says the Hollywood Reporter, adding that several Aspen alumni are due for the gathering.

Also on tap is a “Sex in Aspen” symposium, in which star/executive producer Sarah Jessica Parker, writer/executive producer Michael Patrick King and female writer-producers of the show will talk about how its creators’ private lives have inspired it, according to the USCAF.

Meanwhile, Williams is rocking Iraq, where the “Good Morning, Vietnam” star launched into his bawdy routine on the outdoor stage at Baghdad International Airport on Tuesday by yelling, “Goooood morning, Bagh-dad!”

The Associated Press reports that Williams, 51, headlined a U.S. military show that also featured actress Shannon Tweed, wrestler Kurt Angle and stock car driver Mike Wallace.

Williams reportedly surveyed the crowd of 200 American and Australian soldiers in their camouflage and other military garb and declared them fashion-ready for the streets of Los Angeles.

“I’m looking at a group of heavily armed people here,” Williams joked with the soldiers, most of them armed. “I’m telling myself, ‘If you’re not funny, it’s a problem.'”
