Once upon a time, this guy named Fred decided that he was rough and tough enough to seek his fortune in the Wild West. (This was in the days when the Wild West meant Texas and Arizona, with indians, outlaws, tornados and droughts--not the current situation, where the Wild West means California and you have to brave hottubs, mellowspeak, fires and earthquakes. That is, it was a simpler time.)
So, Fred found his way to a frontier town and became the bartender at the wildest saloon in the territory. He soon proved how rough and tough he was, and the owner of the bar was pleased with how he broke up fights and didn't skim too much off the receipts. He told Fred that he (Fred) was doing a fine job, but he should remember one thing: "If you ever hear even a rumor that Mad Martin is coming to town, just save what you can, put a bottle of Red Eye on the counter, and head out of town as fast as you can."
Fred was pretty perplexed at this, and sought explanation. He was told that Mad Martin was an old mountain man who lived up in the hills and only came to town once or twice a year. However, Martin was the most dangerous guy they'd ever heard of and few had ever encountered him and lived to tell the tale. Fred listened carefully and then promptly forgot all about it.
Until, one day a few months later, a cowboy came riding through town at full speed, yelling, "Martin's coming! Head for the hills!" The result was incredible. Everybody in town immediately jumped on their horses and took off for the hills. Except Fred. He wanted to see this guy because he didn't believe he could be all that tough. So, Fred just put the bottle of Red Eye on the bar, hid behind the counter, and waited.
He didn't wait long. Soon there was a noise in the street. As Fred looked out a hole in the wall, he saw this huge, mean-looking guy ride down the center of the street on the biggest bull buffalo that Fred had ever seen. The guy stopped the buffalo in front of the bar, jumped off the beast, punched it in the head (dropping the critter to its knees) and bellowed, "Wait here til I get back!" The fellow turned and walked up the steps. Fred saw that the guy had a pair of huge mountain lions on leashes. He tied them both to a post and kicked them soundly, hollering, "You pussycats stay here til I'm done!" The cats fearfully sat down.
Into the bar stormed the fellow, ripping the doors off the wall as he passed. With two strides he approached the bar, picked up the bottle of Red Eye, bit off the neck, and downed it all in one gulp. Poor Fred, thoroughly frightened by now, let out a little whimper. The guy looked down over the bar and roared, "What the hell do you think you're looking at!?"
Fred managed to say, "N..n..n..nothing, mister. Do you want another bottle of Red Eye?"
To which the fellow replied, "Hell no! I don't have time! I gotta get out of here--Mad Martin's coming!"
