Jim Halpert: What are you doing?
Dwight Schrute: Just clearing my desk. I can't concentrate.
Jim Halpert: It's not on your desk.
Dwight Schrute: It's overlapping. It's all spilling over the edge. One word, two syllables: demarcation.

Dwight Schrute: You can't do that.
Jim Halpert: Why not?
Dwight Schrute: Safety violation. I could fall and pierce... an organ.
Jim Halpert: We'll see.
