3 men walk into a bar; A Russian, an American, and a Mexican. They all order a beer and sit down to drink. The Russian drinks his beer first then throws it out the window. The bartender asked him why did he throw out his beer, the Russian said he had a lot of those in his country. The Mexican drinks his beer and throws it out the window too. The bartender asked again, "why did you throw it out the window?''. The Mexican said he had a lot of those in his country. The American grabs the Mexican and throws him out the window. The bartender asked the same question again. The American said "I have a lot of THOSE in my country!"
