Season 5 Episode 17:
J.D.: Zip it! I am so gee darned pissed right now. I was okay when you kept me at arm's length because everyone said that was just Cox, that's how he operates, and I believed them. Now I walk in on this, this... bi-racial love fest! You know what? I hate to do it but I'm giving you back the pencil. That's right, the pencil you gave me on my third day of work. You handed it off to me like a tiny yellow baton, but you were trying to say to me "JD you are the new me. You, JD, are my mentee. You, are my son."

"bi-racial love fest" hahaha!
