Cartoon and Bad words

Man these days you even have to preview cartoon to make sure there are no bad words in them! My son was watching a superman cartoon. He came out and told me it had 6 bad words in them????? Six bad words in a cartoon!! That is just ridiculous. He told me I know why they have bad word in them Hollywood made them! HAHAHAHAHHA! Thank goodness I have children who strive to do what God wants them to and are very careful not to repeat things they have heard! I am very thankful for that!
