Quote from Murray in This is This is Spinal Tap
Doctor: How long have you had this mole? Beverly: There a problem? Doctor: No, it's just a bit abnormal. It's probably nothing, but I'd like to do a biopsy, just to be safe. Murray: Ah, the "just-to-be-safe biopsy." Again with the upsell. Doctor: Your insurance covers it. Head two doors down. It's not gonna cost you anything. Murray: Hoo-hoo! You hear that, Bevy? This clown's giving away free biopsies. Quickly, show him your blotches.
