1. The Hilarious 'Arm-Wrestling' Story of How They Met
The origin story of Charlie Day and Mary Elizabeth Ellis’s relationship is far more charming and less chaotic than any episode of Sunny. The couple first met in New York City in 2001, years before they would share the screen.
Ellis was working on a play when Day spotted her at a bar. In a move that sounds straight out of a sitcom script, Day and a friend noticed Ellis and her friend, and Day decided the best way to determine who got to talk to Ellis was a friendly arm-wrestling match with his friend.
Day won the impromptu contest, and the rest is history. They began dating immediately and tied the knot five years later on March 4, 2006, in New Orleans.
2. The Irony of Their On-Screen vs. Off-Screen Relationship
Perhaps the most famous—and ironic—aspect of their shared career is the stark contrast between their fictional and real-life relationship. On It's Always Sunny in Philadelphia, Mary Elizabeth Ellis plays "The Waitress," the object of Charlie Kelly's (Charlie Day) obsessive, often disturbing, and unrequited affection.
The Waitress is famously disgusted by Charlie and constantly tries to avoid him, a dynamic that has been a central running gag for nearly two decades.
In reality, Day and Ellis are a devoted, long-married couple who have worked closely together for years. This professional/personal duality highlights their incredible acting abilities, as they convincingly portray two characters who are polar opposites of their actual relationship. Their ability to maintain this comedic friction while being married to one another is a testament to their dedication to the show.
3. Her Major 2024 and 2025 Projects Cement Her Star Status

4. The Meaning Behind Their Son's Unique Name: Russell Wallace Day
Charlie Day and Mary Elizabeth Ellis welcomed their first and only child, a son named Russell Wallace Day, on December 15, 2011.
The name Russell Wallace is a touching tribute to their family history. Russell is a name from Ellis’s side of the family, while Wallace is a tribute to Day’s own family.
The couple is notoriously private about their son, though Charlie Day occasionally shares anecdotes about fatherhood in interviews and on *The Always Sunny Podcast*. Russell Wallace Day is now a teenager, and the couple has successfully kept him out of the intense media spotlight, prioritizing his privacy.
