Let's make this birthday one to remember.

45 years old (Born on March 14, 1980)

Happy Birthday, Mercedes McNab! From your unforgettable portrayal of Amanda Buckman in "Addams Family Values," teaching us all the perils of overly enthusiastic camp counselors and Thanksgiving pageants gone hilariously wrong, to your iconic role as Harmony Kendall on "Buffy the Vampire Slayer"—you've always brought laughter and charm into our lives.

Whether you're delivering witty vampire banter or perfectly timed comedic lines, you've consistently proven that humor is timeless. May this birthday be filled with joy (and hopefully fewer vampires than Sunnydale), because let's face it: no one handles supernatural drama quite like you do. Cheers to another fantastic year ahead!
