Marshal Sandy Hopkins : Who, me? I was just tryin' to place that hombre drivin' that stage. He sure looks familiar. No, that's funny, but I will! I got a memory like an elephant. I never forget a face. No, siree!
Ed Scully : Yeah? Well, it ain't healthy to have too good a memory around here. Go on. Get back to your work!
Marshal Sandy Hopkins : Yes, siree.
Marshal Sandy Hopkins : [role-playing janitor when he knows Scully can hear] Well, glad there ain't no hard feelin's fella.
