While enjoying the silliness I realized that this show is a good example of Proverbs 22:6, "Train up a child in the way he should go: and when he is old, he will not depart from it."
Each episode starts with lessons or experiences that Shawn and Gus have when they were children. The episode then shows how that experience or lesson correlates with what they are doing as adults. They go through all the shenanigans and usually end up getting advice from his dad, and then solving the case. It's a good reminder for us that as we have our own children, or influence children, to be careful what you teach them. It will effect the rest of their lives.
