The part where Peters friend is in the school computer lab helping Peter and gets caught by the principal, who asks him what he is doing, to which he hesitatingly replies, "looking at... porn...", which elicited a good laugh from the audience. I went with a buddy of mine and we both have boys who are about the same age, 9-10. His son, after that line and the audience quieted down said loudly, "Dad, what's porn?" which got a lugh at least as big from the people around us, haha
