Three billionaires walk into a bar. The first billionaire throws up his hands. "We're broke," he cries. The second billionaire throws up his hands. "We're broke -- all of us," he sobs. The third billionaire throws up his hands but before he can say anything, the bartender rushes over and shouts out, "you guys don't expect me to foot the bill again, do you?" The third billionaire smiles: "How do you think we became billionaires?"
