WATCH: Megan Mullally, Nick Offerman Question Quickie Vegas Weddings While LGBTs Can't Marry Legally

 Actors Megan Mullally and Nick Offerman wonder why gay and lesbian couples who have literally spent their whole adult lives together can't get married when any random man and woman can show up at a Las Vegas chapel and tie the knot.

Mullally, a longtime equality advocate who is best-known for her Emmy Award-winning work on Will & Grace, and Offerman, who current stars on NBC's Parks & Recreation, have been married since 2003. In the humorous ad, the couple jokes that the night they were married she thought she was marrying Cedric the Entertainer, before complaining that “Any random man and woman can casually show up at a 24 hour wedding chapel in Vegas, exchange ‘I do’s’ and boom – they’re married. ”Why can't gay and lesbian couples who have literally spent their whole adult lives together have the same opportunity?" The video message is part of HRC's Americans for Marriage Equality, a campaign that features prominent Americans who support committed gay and lesbian couples getting married.

“The discrimination that committed and loving gay and lesbian couples face every day doesn’t benefit anyone,” says HRC President Joe Solmonese. “Megan Mullally and Nick Offerman poignantly remind us that it’s time to end the exclusion of gay and lesbian couples from marriage.”
