Megan Mullally has been treading the Broadway boards these days in the hit revival of Terrence McNally’s It’s Only a Play, about the opening night shenanigans of a new Broadway show. The role is a welcome stage return for Mullally, who appeared on Broadway in Grease and How to Succeed in Business Without Really Trying long before she ever waxed Karen on Will & Grace.

She’s the latest star to drop by EW’s studio for our Firsts & Worsts series, which dives into Broadway stars’ theater pasts—because deep down, we’re all brimming with community theater horror stories, right?

Watch Mullally revisit her own firsts and worsts, including her bizarre headshot experience, the worst show she made her parents sit through, and the unconventional singing advice that didn’t exactly pan out.
