One day a horse walks into a bar. He looks at the bartender and says,"Sam, get me the usual."

"Comin' right up," replied Sam.

When the horse goes home he is all drunk. His wife takes him into the kitchen and says,"Mike! Stop coming home drunk! I've told you this before, and I'm sick of it! If you come home drunk one more time and scare the kids, we're out of here!"

The next night, Mike goes back to the bar. This time he orders a root beer. Sam the bartender looks at him and says,"Hey Mike, why the long face?"
