"Get Smart: The Only Way to Die (#2.4)" (1966)
Agent 13: I'm sitting in a mailbox and you're telling me I don't know what it's like to be cooped up in a small room? I'd love to be cooped up in a small room. I'd give anything to to be cooped up in something as big as a small room.
Maxwell Smart: Take it easy, 13, take it easy.
Agent 13: Every assignment I get I'm always locked up in something small. I'm always in a mailbox or a scale or a locker or a grandfathers clock or a tree - you know what happened when I was stationed in that tree at the rubber plantation place?
Maxwell Smart: What?
Agent 13: I was tapped! Try that some time! Try standing up all night with a spigot in your stomach!
Nice work Maxwell Fre_Doh. Were you contacted by shoe phone?
