Doctor's remedies

One day a man named Guy was walking to work and on his way, he tripped and fell, which in turn scraped his knee fairly badly. He thought it would be a good idea to ditch work and go to the doctor's office to get his knee checked out. He went into the doctor's office and saw the place was fairly busy. When finally got to meet with the doctor, he said:

> Guy: DOC! Ya gotta help me! I tripped on the pavement on the way to work and scraped my knee. How do I fix it?
>
> Doc: It'll be okay my boy, look, I'm kinda busy today, so just get this ointment from the pharmacy and apply it on wherever you got hurt for the next 2 weeks, and then come back and follow up with me.
>

Guy then uses his new ointment for the next 2 weeks and goes back to the doctor's office. They converse:

> Guy: Doc, I've been using the ointment for th past two weeks, but there doesn't seem to be any improvement, what gives?
>
>Doc: Lemme see where you scraped yourself,
>
>Doc: EW! This is an infection now, did you even use ointment on here?
>
>Guy: OOOOOHHHH! I was supposed to put the ointment on where I got hurt?
>
>Doc: YES! WHERE DID YOU APPLY IT THEN?
>
>Guy: I applied it on the pavement where I fell, right on the corner of Main St. and Birch Blvd.

>Doc: ಠ_ಠ
