Dr. Yoho's adventure with a horse in Buenos Aires

Dr. Yoho took a trip to Buenos Aires to attend a medical meeting about cosmetic surgery.  During the trip, he went into the countryside and did some touring and jumped on a horse for the first time in 20 years. 

He was having a wonderful time until the horse found that he was on his way back to the corral at the end of the ride and began to break into a faster pace.  Dr. Yoho was anxious about the horse's speed and was afraid that he'd fall off, so he pulled back on the reins and the horse bucked him right off. 

While Dr. Yoho insisted that he fell gracefully, close observers claim that he looked like a sack of potatoes as he flew through the air and hit the ground.  Fortunately, very little was bruised except for his right buttock and his ego, and he continued on the sightseeing trip with no further mishaps.
