....it seems that the animal-trainer at the Ringling Bros. Circus had two village idiots as assistants. He employed them primarily to clean out the cages and holding-pens. They were constantly bugging him to let them ride a camel. When the circus came into a town, there was always a parade with elephants, camels and horses. The head trainer finally relented and gave the idiots the oldest and most docile camel to ride.
Off they went. Whenever they rounded a corner with a crowd, there was cheering, jeering, and other commentary. AZfter passing each crowded arfea, the rearmost rider bailed out, ran around to the camel's rear, lifted the tail and studied what he found under there. After about six of these incidents, the "driver" blew his stack: "Stanley, whatterya doin'? You're makin' the people laugh at us!"
Stanley said: "Well, every time we go by a crowd, someone always yells: 'Look at the two assholes on that camel!'---I was just checkin'...!"
