Happily wedded Hollywood sweethearts Megan Mullally and Nick Offerman make beautiful music together -- and comedy, too! And -- lucky Denver! -- Mullally will be singing her heart out with Stephanie Hunt as "Nancy and Beth," while Offerman offers a sneak peek at his American Ham solo show when they share their charismatic acts during a benefit performance on September 7 at the Ellie Caulkins Opera House.

We're giving away a pair of tickets so that you can see them live -- but first, we're treating you to our ten favorite moments of Mullally as Karen in Will and Grace. What's your favorite Karen scene? Post it below by 5 p.m. Tuesday, September 3 -- and the best memory will win two tickets to see Megan Mullally live on September 7!
