Joke About Mexicans

Alright listen up, you are probably one of those soft people who think that jokes are not cool. This joke is funny because the dude is saying that he was going to make a joke about Mexicans. But he is stopping himself and admits that it "crosses the line". Basically, he wants to make a joke, but knows that it might be offensive. I bet you have never even seen a Mexican, you wouldn't last a day in Mexico.
