Scrubs, Season 2

J.D.:
Look... Janitor, I'm gonna be straight with you. I saw your penis and I noticed a possible melanoma that you should really have checked out.

Janitor:
When did you see my penis?

J.D.:
Last night when you were showering.

Janitor.:
Where were you?

J.D.:
Oh, I was outside in the bushes.

Janitor:
[dumbfounded]

J.D.:
Look, it was just a coincidence, man. If you had looked out of the window you would've seen MY penis, you know.

Janitor:
What? Why?

J.D.:
Because I had it out while I was looking at yours!
