Kids bring in presents for their teacher on the first day of school. The teacher can tell what the child's parents do by the present he brings, such as apples from the parent's fruit stand, a baker's child bringing rolls, and candymaker candy. The last person brings in a crudely wrapped package with yellow liquid leaking out. The teacher tastes the liquid and states that his father must run a bottling factory. The child replies that no his dad is a dogcatcher and that it is a puppy in the package.
