A man walks into a bar, and as he makes his way to the counter, he stops and talks to everyone in the bar. As he finishes with each group of people, they all get up and leave and go stand outside the window, looking in. Finally, the bar is empty except for this guy and the bartender. The man walks up to the counter, and says to the bartender, "I bet you $1,000 that I can spray beer from my mouth into a shot glass from thirty feet away, and not get any outside the glass."
The bartender thinks that this guy is a nutcase, but he wants his $1,000, so he agrees. The bartender gets out a shot glass, paces off thirty feet, and the contest begins. The man sprays beer all over the bar. He doesn't even touch the shot glass. When he finishes, the bartender looks at him and says, "Well, I guess you owe me $1,000, huh?"
The man answers, "Yeah, but I bet all of those people outside the window $500 a piece that I could come in here and spray beer all over the bar."
