Swedish Shell Game

I glanced around the platform to ask one of the local citizens, but none could understand me, so I turned back to The Bishop who was examining the three receptacles.

"Is it like the two buttons, or the three shell?"

"I'm not sure," he replied, staring down into the one on the far right.

"Well, do we segregate our rubish according to shape? Round peg in the round hole?"

Bishop nodded, "Perhaps you are right."

"Thought so. Let me see what happens when I try to stuff your ticket into the round hole."

An expected furrowed-brow-stare turned my confusion into mirth.
