Debra Messing and Eric McCormack discuss 'Will & Grace' legacy, karaoke, and 'Breaking Bad'

Debra Messing and Eric McCormack know their way around a joke.

The duo kept fans laughing for eight years on Will & Grace, and now –since it has been 15 years since Will & Grace premiered — Messing and McCormack stopped by EW to reminisce, not to mention continue to crack us up.

The two’s fan-favorite chemistry was on display when they took EW’s Pop Culture Personality Test together, teasing each other while Messing shared her Meryl Streep love and McCormack discussed just how many karaoke CDs he own (Hint: It’s a lot.)

The laughing continued when the duo talked about their thoughts on Will & Grace‘s legacy. Messing told EW that the episode people most often approach her to gush about is the “exploding water bra” from the episode “Das Boob.” For McCormack, it’s the series finale. “I get people coming up to me wanting to talk about that last scene,” he explained. “The idea that there were these two young people that everyone in the audience assumed was us, in flashback, and then when they realized it was our kids, the gasp from that audience, and then us coming in as people in our sixties, everyone always says they cried.”

Watch below for more from Messing and McCormack, where in addition to answering our questions about first celebrity crushes and television moments they’ve rewound, fans can see that the two should really consider a musical recording together — if only they could remember all the words to said duets.

Will & Grace is now newly in reruns on WEtv, where it airs weekdays from 5:00-8:00 p.m. ET, as well as all night on Tuesdays beginning at 8:00 p.m.
