Sad Mary is a character that appears in the Cyanide and Happiness short Sad Larry in Love. It is unknown if she will ever appear again.
Sad Mary is essentially the female equivalent of reoccurring character Sad Larry however, she is less compassionate than Sad Larry and can get angry and offended just as easily as she can get depressed. She also has a job as a waitress at the local dinner.
In Sad Larry in Love, she first appears in a scene very similar to the episode Sad Larry when Sad Larry calls her over and attempts to flirt with her. She then started crying and asked if he's making fun of her. When he tried to backtrack, she kicked his food in his face and stormed off exclaiming, "I'm sick of this shit!"
Sad Mary has dull brown hair pulled back in a ponytail and always sports a depressed expression similar to Sad Larry's. She wears a dark blue shirt with a white apron and a pin with a frowny face.
- If she does not appear again, she is one of the most developed one-time character and the most for a character that the episode doesn't focus on.
