VIDEO: 'Will & Grace' Stars Debra Messing, Eric McCormack Reunite on TODAY

'Will & Grace's' Eric McCormack and Debra Messing stopped by this morning's TODAY on NBC for a special reunion marking 15 years since the show premiered. Check out the appearance below!

The NBC series followed a gay man and a straight woman sharing an apartment, a revolutionary idea in 1998. "We used to be asked about (the lasting social impact) while it was on," McCormack said. "That's when we didn't want to say anything; we were just a comedy, we were just trying to be funny. But now with time ... what I'm most proud of is that we always treated, the show always treated, Will's desire for the perfect man as equal to Grace's desire for the perfect man. ... That was the real message."

Both actors knew from the start that the chemistry between them was something special. "I was too superstitious to say it out loud, but he turned to me after we shot the pilot ... and he said, 'I think we're going to be together for a long time,'" recalled Messing. "And I got chills."

"Will & Grace" reruns are now airing in mini-marathons on WEtv.
