A German, an Italian, an American, and a Mexican are sitting on a roof... celebrating after a hard days work. The German pulls out a bottle of beer, takes a long chug and throws the rest of the bottle off the roof. The Italian asks, ""Why did you waste that?"" The German replies, ""Don't worry, we have so much beer in Germany."" The Italian then pulls out a bottle of wine, takes a long chug and throws the rest off the roof. The German asks, ""Why would you do that?"" The Italian replies, ""Don't worry, we have so much wine in Italy."" The American then grabs the Mexican and throws him off the roof. Both the Italian and German jump up and yell, ""Now why would you do that???"" The American replies, ""Don't worry, we have so many Mexicans in the America.""
