Ge You’s lines in the mental hospital

From the film "Who Says I Don't Care" starring Feng Gong and Lu Liping, the story goes like this -

There was a mental patient who kept mumbling all day long: "Look for someone." Use a rubber band to make a slingshot and hit your glass." He said this to everyone, and this matter has almost become the entire meaning of his life. The doctor treating him was so worried that he tried countless methods but to no avail. He felt dizzy when he heard the word "slingshot", as if there were three mountains pressing on his head. One day, he and the patient were walking on the corridor of the hospital, and the patient still kept talking about looking for a rubber band. The doctor was quite upset, so he looked at the scenery outside the window to relieve his worries. He suddenly saw two well-dressed sexy beauties upstairs opposite him. His heart moved and he hurriedly pulled the patient over and let him see them. When the patient saw the beauty, his eyes lit up and he smiled. The doctor struck while the iron was hot and asked, "What do you want to do now?" The patient said, "Hey, I want to take off their clothes." The nurses on the side whispered that they were gangsters, but the doctor said, "Shh, he is starting to think like a normal person. He asked again: "What's next?" The patient blushed and said, "I want to take off their pants." The nurses were already booing, but the doctor was excited and asked the question: "Okay, go ahead and continue with you." What do you want to do?" The patient lowered his head and said, "I'm going to take off their shoes and socks." "What else?" "I'm going to take off their pants." The doctor looked at the patient step by step. Suppressing the ecstasy in my heart, I asked again: "Then, what are you going to do next?" "Hey, I'm going to take out the rubber bands on their pants, make a slingshot, and hit your glass!"
