I like to include a little note or a joke in my boys' lunch boxes each day. However, this can get time-consuming and if I'm in a rush, I can forget. Now, I purchase a daily desk calendar for each son (I get them 50% off after Christmas!) and just rip off that day and stick it in their lunch. This year my older son has the Big Nate calendar (based on the book series) and my younger one has Peanuts. Quick and easy!
