The Yawner

"During his daily promenade, a fine gentleman in his impeccably crisp suit wearing a black and broad-brimmed top hat is yawning incessantly."

A top-hatted man gets dressed in the morning, and starts to yawn, causing his housekeeper to yawn as well. He sets off down the street where he proceeds to make others yawn as well, including a shop keeper, passers-by, and a small group of soldiers.
