what do you call four dead mexicans in the bottom of a lake ? quatro cinco .
Why do you find dead mexicans funny?
What the hell is there to explain? Don't split hairs. It's funny because mexicans are living on earth and just die.
It's not right to joke about a group dying. It's insulting to those involved. Being more considerate of the group would help go a long way in not offending Mexicans.
