The Lone Ranger and Tonto go into town to get supplies and stop in at the local bar for a cold one. While in the bar a gentleman comes running in frantic and says "Who owns that white horse tied up out front?"
Lone Ranger says "That's mine- Why?"
Gentleman says "Cause it's lying on the ground all foaming at the mouth".
Lone Ranger runs outside and finds that his horse, Silver, has overheated. He moves the horse closer to the water trough, but Silver still doesn't look too good.
Gentleman says "I think he needs some air circulated around him."
Lone Ranger says "Tonto. Run around Silver to stir up a breeze" Sure enough Tonto begins running and the Lone Ranger goes back inside to finish his cold one.
Short time later another gentleman comes running into the bar and says "Who owns that white horse out front?"
The Lone Ranger says "Not again. NOW what is wrong?"
Second gentleman says "Not much, but I think you left your injun running"
