Open Sesame

While I was walking down the hallway, Otto, who was in front of me, stopped abruptly.  He spread his arms wide, hands touching each of the walls, and blocked my way.

He looked at me and said "Sesame Street!"

As my questioning words of "Sesame Street???" were being formed and tumbling out of my mouth, my brain clicked in and I got it.

"Say 'Open Sesame Street!'" he exclaimed.
