Indian Blanket.

A cowboy and his Apache friend take to the hills in search of diamonds that are rumored to tumble down-stream in the fast moving waters that are so cold it freezes your skin the moment you dare to stick your hand in to grab the bouncing, sparkling rocks that hold the most valuable mineral of them all. The Apache know how to determine where the diamonds might be, and the cowboy and his friend locate a place where the pickings are easy, but it's not to long before they are found out by a passing Desert dog that feel lucky enough to try and rob them of their new found wealth.

The Desert Dog is so eager to take the diamonds from the cowboy, he forgets about the cowboy's friend and is ambushed not by gunfire or even a thrown fist, but is knocked down by a blanket, an Indian Blanket and then is nearly trampled on by the cowboy and his horse.
