I am reading the above book, The Laughing Classroom, with the book club at school. In an effort to break up the "seriousness" of my kindergarten classroom, we took a few moments to share some "Knock, Knock" jokes.
Student 1: Knock, knock. Who's there? A tree. A tree who? A tree wearing pants!! hahahahahaha!!!
Student 2: Knock, knock. Who's there? Peas. Peas who? Peas that are wearing shorts! hahahaha!!
Student 3: Knock, knock. Who's there? A man. A man who? A man who's got pajamas on and sleeping at school! hahahahahaha!!! (This was my favorite because it was pajama day, and this student just thought it was hilarious. I could picture his surprise that morning when his mother told him to get dressed for school and handed him pajamas.)
Student 4: Knock, knock. Who's there? Big mama! Big mama who? Big mama got jam!! hahahahahahaha!!!!!
Kindergarteners really know how to tell a good joke! : P They had me rolling, because they were laughing so hard at the silliest stuff. They loved it and always ask for more.
