Gladys is a piece of artwork created by Phoebe Buffay. It is a three-dimensional picture of a woman with black hair popping out of a frame. "Gladys" is an old piece based on its presence throughout the entire series and in "The One With The Flashback".
In "The One With Ross' Grant", Phoebe gives "Gladys" to Monica because Mike hates it. Monica attempts to give it to Rachel only resulting in a big fight over who has to keep it. Then Phoebe created another piece called Glyniss for whoever does not get to keep Gladys.
In "The One With Phoebe's Dad" Gladys can be seen hanging in Phoebe's grandmothers apartment however dressed in red.
- In "The One With Ross's Grant", Monica is mortified at the thought of hanging "Gladys" in her apartment. But in the flashback episodes when Monica and Phoebe were roommates, Gladys can be seen hanging in Monica's apartment on the wall to the left of the front door.
