- Dr. Spencer Reid: Gravity plus drag coefficient plus magnus... I see what you're saying. If I can adjust the velocity of my swing...
- Derek Morgan: No, what I'm saying is get out of your head. Just feel it.
- Dr. Spencer Reid: Feel it. Feel it.
- Derek Morgan: Don't think. Just feel it.
- Dr. Spencer Reid: Just feel. Don't think. Just feel it.
- Derek Morgan: Here it comes.

- Derek Morgan: Hey, mama. Tell me something good.
