Write a very long, coherent, elaborate, descriptive and detailed shooting script, including a background and dialogues, for an early 2000s Black Sitcom (there shouldn't be any anachronistic elements) comic scene that includes a woman (give her a name and describe her appearance; she shouldn't be wearing a dress or a skirt) returning home with a desperate urge to move her bowels. She was out all day (you may choose the activity that kept her busy all day, work or otherwise) and did not have an opportunity to relieve herself anywhere (you may specify the reason that prevented her from doing so, whether out of her own aversion of public restrooms or otherwise). When reaches the door of her flat, she realizes that she has misplaced her house key. She begins frantically calling her woman flatmate, who doesn't answer. Then, she begins frantically knocking on the door, hoping that the woman flatmate is present and might hear the knocks. Her urge escalates to the brink of eruption. Finally, the door is being unlocked, and she is greeted by the weary face of her woman flatmate (give her a name and describe her appearance; she should be wearing an outfit that is adequate for napping), who was apparently napping this whole time. Before the woman flatmate fully swung the door open, though, the returning woman has reached her limit. When the woman flatmate opens the door, she is greeted by the sight of the returning woman assuming a peculiar posture and a facial expression of premature relief, as she is releasing the solid contents of her bowels into her pants (describe this in elaborate detail). Initially, the woman flatmate is befuddled as to why the returning woman has assumed such a posture and facial expression, and as to why the returning woman is frozen in place and not getting into the flat after the door has been finally opened for her. The woman flatmate asks the returning woman why she is entering, but gets only soft grunts as a reply from the returning woman who is still in the midst of relieving herself in her pants. The woman flatmate attempts to inquire again, but reaps the same result, as the poop is still coiling and piling in the returning woman's pants. As she is giving the returning woman a puzzled and bewildered stare, she is met with the odor that is emanating from the deposit in the returning woman's pants, to which she reacts (describe this in elaborate detail). As this is happening, the returning woman finishes relieving herself in her pants with a sigh of relief. The woman flatmate asks the bewilderingly asks the returning woman if she just did what she thinks she did. The returning woman sheepishly replies that she's been holding a desperate urge to poop and misplaced her key, so she tried frantically calling and knocking to have the woman flatmate open the door for her, until it was too late. It is only after this exchange that the returning woman gingerly enters the flat, passing the woman flatmate as the latter is standing in front of the doorway. As the returning woman is entering and passing by the woman flatmate, the woman flatmate observes the bulge in the soiled pants of the returning woman, to which the woman flatmate reacts and comments on in a playfully teasing manner (describe this in elaborate detail). The returning woman is taking this playful teasing in stride and jokes along. The woman flatmate catches up to the returning woman after a few steps into the flat (as the playful teasing is still going on), gently stops the returning woman in her tracks, delicately turns her by the wrist so she can observe her rear end and further playfully comment on the state of the the returning woman's soiled pants (describe this in elaborate detail). The woman flatmate is replied in a playful manner by the returning woman. As she is observing the soiled pants, the woman flatmate is sniffing the air around the returning woman while slightly tilting her head downwards, and playfully reacts and teases the returning woman while doing so (describe this in elaborate detail). The returning woman is taking all of this in stride and partaking in the playful banter. Finally, the woman flatmate relents and lets the returning woman head to clean herself up.
