Jesse Tyler Ferguson to appear in theater sitcom "Submissions Only"

(CBS/AP) NEW YORK - Jesse Tyler Ferguson might be a star now, but he remembers sweating it out in front of casting directors.

The "Modern Family" actor is revisiting those early tough days in a cameo for "Submissions Only," a new online scripted sitcom now wrapping up its second season that takes a behind-the-scenes look at the life of theater hopefuls.

Each episode begins with an audition and the one featuring Ferguson - which airs April 27 on BroadwayWorld.com - has him belting out an original song - and crashing and burning.

"I've had many horrible, horrible auditions," Ferguson said. "They're tucked away. I try not to remember them."

He added, "It's sort of the actor's nightmare. You get in your head too much and you start second-guessing everything too much."
