Yes, we live in a fallen, sinful, and evil world. But we serve a risen Savior who I believe has a playful humor. At the very least he is full of joy and has come to impart that joy into our hearts that we might laugh again and realize that in the end all our sadness will be reversed. That is what resurrection means. And therefore, we too can laugh, have joy, and not take ourselves so seriously all the time. Perhaps a playful humor can reflect the very character of the Savior we serve and draw people to the joy found only in him.
