A man walks into a bar.......

The man goes to the bar, and takes a seat on a stool. He proceeds to ask the bartender for two shots of his special whiskey. Upon receiving the whiskey, he turns to the side, and tells the man sitting there," This is magic whiskey. If I drink it, I will not die." So the man gives his fellow bar member a shot of whiskey, drinks his own, and walks out to the street. He jumps in front of a speeding car, and comes out unscathed. The other bar member, amazed, drinks his shot of whiskey, and jumps in front of another speeding car, and is run over and killed. The first man walks back into the bar, and orders another drink. As the bartender was giving the drink, he shakes his head and says," That's not funny, Superman."
