As Karen Walker would say, “Honey, what is this? What’s going on? What’s happening?” While the circumstances are unclear, Will & Grace stars Eric McCormack, Debra Messing, Sean Hayes, and Megan Mullally recently got together for a reunion and posted photos from their time together on social media.

The quartet played Will, Grace, Jack, and Karen in the beloved sitcom. Messing tweeted a photo of their reunion with the caption, “Only smiling because of where Eric’s hand is!” Mullally channeled her boozy character in response: “I’m smiling, too, and not just because of a hand.”

According to a tweet from McCormack, the reunion occurred last Wednesday. See the photos below.

Will & Grace ran for eight seasons from 1998 to 2006. McCormack and Messing came back together a few years later in 2010 for EW’s Reunions issue.

“Obviously, we’re very comfortable with each other,” Messing said at the time. “I mean, after nearly a decade of working together, we have a shorthand that will always be there.”
