Two drunks are walking along. One drunk says to the other, "What a beautiful night, look at the moon."
The other drunk stops and looks at his drunken friend, "You are wrong. That's not the moon, that's the sun."
Both started arguing for a while when they came upon another drunk walking, so they stopped him. "Sir, could you please help settle our argument? Tell us what that thing is up in the sky that's shining. Is it the moon or the sun?"
The third drunk looked at the sky and then looked at them and said, "Sorry, I don't live around here."
