Fred Armisen, Patton Oswalt

Before ABC's Modern Family heads to Australia next month, they will be taking a trip a bit closer to home. This week, the six adult cast members will go on location to Las Vegas, where they'll be joined by two high-profile guest stars.



Fred Armisen, of Saturday Night Live and Portlandia fame, will play Langham, one half of a gay couple who'll have fun with Mitch and Cam. And funny guy Patton Oswalt, who has appeared on Reno 911!, Two and a Half Men and The United States of Tara, will play a magician named Ducky Schindler who crosses paths with Phil.



The episode is expected to air this spring.
