There's a Sketch in This

I walked in to my neighborhood 7-11 this evening and the clerk on duty knows me so well, he has what I want before I get to the counter. I wonder what would happen if I just wanted to buy a lottery ticket. Anyway, he asked me to explain the meaning of collective bargaining which I did. All I can envision is me riding into the night, and someone saying "Who was that man?", and someone else replying, "That was the Lone History Teacher!" It would be something in the vein of Monty Python.
