The Church Skits website and Christian Crafters website both offer skits for Pastor Appreciation Day, including "Three Cheers for Pastor!" by Karen Werkmeister. The simple free puppet show is used in many Sunday School classes.
"Pastor and Wife Appreciation Skit" by Tanis Harms is a free skit available from the Church Skits website. It offers the message that, "a pastor always cares." There are also several skits available for purchase at the Skits and Stuff website. For more ideas or just a good laugh, "The Pastor's Chair" is a video skit about what really goes into the job of pastoring, available for view at The Skit Guys website.
