Hi Ty, Like your sense of humor. You are right the joke is a "groaner" but students like that kind of thing to get a class started. I have found that they not only like these kind of things they quickly grow to expect them. They start to bring things like jokes or cartoons in to share with the class. This lets me know they are enjoying it plus are thinking about their class even when it is not in session. This helps in bridging between school and their outside lives. Keep up the good work. Suggestion don't quite your day job to be a comedian. Gary
