A guy was trying to console a friend who'd just found his wife in 
bed with another man. 
"Get over it, buddy," he said. "It isn't the end of the world."
"It's all right for you to say," answered his buddy.  "But what if you
came home one night and caught another man in  bed with your wife?" 
The fella ponders for a moment, then says, 
"I'd break his cane and kick his seeing-eye dog in the ass."
