Fred Rogers' religious foundation becomes apparent in this episode as he hears an explanation of what a pretzel represents: Originally, pretzels were "given to children for knowing prayers" in Germany. As they are made, pretzels are first shaped "like a great big U. Take one [side] and cross it over the other. This is to represent children's arms praying to God. Then we take one and fold over the other. That represents your parents - mom and dad. We pick up the ends and fold them on back." When Mister Rogers asks if there always has to be three holes in a pretzel, he is told that the three holes represent the Holy Trinity.
The segment where Mr. Rogers visits the pretzel factory appears as a bonus on the DVD, Mr. Rogers Goes to the Circus.
