Pretty soon a guy comes in "Who's white horse is that tied outside?"
"Mine", said the LR, "What's it to you?"
"Well, he's really hot and sweaty."
"Tonto, take care of Silver."
"Right away, Kimosabe."
So Tonto takes a blanket off the saddle and starts running around Silver waving the blanket to cool him off.
Pretty soon, another guy comes in. "Who's white horse is that outside?"
"Mine" says the Lone Ranger, "What's it to you?"
