At the Doctor's Clinic...
Patient: Ooh! Doctor, when will this stomach ache go?
Doctor: Don't worry, Just follow this prescription and you will get quick relief.
As the patient stepped out into the waiting room of the clinic, a gust of wind blew the prescription out of the first-floor window.
Patient: Hey! Wait!
Doctor: How did you hurt yourself?
Patient: Doctor, didn't you tell me to follow the prescription?
Doctor: That's right, I did.
Patient: The prescription flew out of the window, so I followed it.
