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!

Next Day...

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.
