After nearly two decades and seventeen seasons, I’m convinced one of the biggest mysteries about one of the gang’s worst enemies inIt’s Always Sunny In Philadelphiawill never be solved.
It’s Always Sunny in Philadelphiaseason 17, episode 3, “Mac and Dennis Become EMTs,” saw the return of The Lawyer, also known as The Attorney (played by Brian Unger). The lawyer last appeared in season 11, episode 7, “McPoyle vs. Ponderosa: The Trial of the Century.”

The Lawyer was first introduced inIt’s Always Sunny in Philadelphiaseason 3, which was released way back in 2007. Since then, The Lawyer has appeared in seven total episodes, including the recently released season 17 episode. Still,after all this time, The Lawyer’s true name remains unknown.
We’ll Probably Never Learn The Lawyer’s Real Name In It’s Always Sunny In Philadelphia
He & The Waitress Will Likely Never Be Identified
Even though The Lawyer has been a sparsely recurring figure sinceIt’s Always Sunny in Philadelphiaseason 3, the audience has never learned his real name. The gang onlycalls him “The Lawyer,” and he’s also credited as The Attorney.
The character only referred to as The Lawyer throughoutIt’s Always Sunny in Philadelphiais similar to The Waitress, played by Mary Elizabeth Ellis.

The character only referred to as The Lawyer throughoutIt’s Always Sunny in Philadelphiais similar to The Waitress, played by Mary Elizabeth Ellis. AlthoughThe Waitress has appeared in more than five times as many episodes as The Lawyer (38), it’s doubtful that we’ll ever learn either of their names.
Why It’s Always Sunny Never Reveals The Lawyer Or The Waitress' Names
It’s One Of The Longest-Running Gags Of The Show
The main reason why the gang refers to The Lawyer and The Waitress by their professions rather than their real names is obviously because it’s naturally funny. It has effectively becomeone of the longest-running gags of the celebrated TV comedy.
Within the narrative context ofIt’s Always Sunny in Philadelphia, it’s clear thatthe gang doesn’t respect either of them enough to call them by their real namesor care enough to remember. The gang mainly sees The Lawyer and The Waitress by their professions and not as human beings.

It’s Always Sunny Season 11 Confirmed Dee Knows The Lawyer’s Real Name
She Looked Him Up On An Ancestry Website
Back inIt’s Always Sunny in Philadelphiaseason 11,Dee looked The Lawyer up on an ancestry site, which is evidence that she had to know and remember his real name, even if she never calls him by it.
It’s uncertain whether The Lawyer will appear again before the eventual series finale ofIt’s Always Sunny in Philadelphia, which could extend its run past its guaranteed eighteenth season next year. Regardless, keeping his name a secret, just like The Waitress’s name, until the very last minute would be a hilarious way to punctuate the beloved comedy series.
