I like how everyone is mentioning that you cursed in front of the kid and that is some societal no-no when he is attending a movie with graphic depictions of violence, sex, and cursing. All things that can corrupt children in some peoples eyes. I find it even funnier that "curse words" still have leverage in society. Words, people they are just words. Teach them their uses and what they mean and don't be so afraid of them.
Also @Wolverine: I live in Central Jersey myself and the rudeness and general lack of humanity by those who identify themselves as being from North Jersey, New York, and fans of the Jersey Shore in any incarnation, be it show or locale, is overwhelming.
Also many of you have never been to the movies in Philly where people from the first row will talk to people in the last row during the movie. I shit you not.
And no reference to the Simpsons yet... I guess I'll do it.
