Here is a run down of my top 10 favorite Will & Grace episodes (at least from the original run).
10. The Finale
Favorite Moment: The ending. After seeing them grow old and grey, Will muses over how they haven't changed a bit... and then they're young again.
9. Hocus Focus
Favorite Moment: Glenn Close separately dry humping both Will and Grace.
8. Ben? Her?
Favorite Moment: The epitome of comedic writing IMO.
7. Secrets and Lays
Favorite Moment: "I don't think it's dead yet."
6. Back Up, Dancer
Favorite Moment: All the dance scenes (sponsored by Penzoil).
5. To Serve and Disinfect
Favorite Moment: When Karen exclaims "This is the end of me. I don't think I can go on..." and then runs to the open window... to grab a bottle vodka.
4. Moveable Feast
Favorite Moment: Every moment leading up to the bell dings.
3. Swimming Pools...Movie Stars
Favorite Moment: A tie between Karen's "I can't believe I'm at a public pool. Why doesn't someone just pee directly on me?" and Will, Grace and Sandra Bernhard's musical number.
2. Von Trapped
Favorite Moment: All scenes referencing The Sound of Music, which is every scene.
1. An Old-Fashioned Piano Party
Favorite Moment: Love will keep us together. #FriendshipGoals
