Surprised And Somewhat Embarrased

I've volunteered for several years at the local childrens' museum.Always enjoy it,and it's amazing at times how much I still learn from them.Had an incident recently though,that caught me by surprise.There was a group of kids in the play doctors office,with one laying on the table while others pretended to operate.Just joking with another volunteer there,I said,OMG,they killed Kenny!I had no idea so many preschoolers knew about South Park,until a number of them shouted out the usual response from the show.
