During the S1E8 episode "Saving Grace", Dr. Pankow is saying goodbye to Shelly and while shaking hands with her, says "such a pleasure to have met you, Shelly...?" to which Shelly, who first looks at Parker, says "...Nemec." She then walks past Parker, who says under his breath quizzically "Nemec?" Nemec is, of course, the real surname of the actor who plays Parker.
