This strip is a great example of what Herky was: an obvious small child who acts like a small child, yet speaks like an adult. Herky is concerned about not getting Christmas presents from Santa, so instead of doing the right thing because he knows he should, he does the right thing so he can receive more rewards, as a small child would. Further, the crimes he is trying to make up for seem like things only kids would do without any thought of the consequences. However, he does this with a level of politeness and articulation that would normally only come out of the mouths of people at least three times his age. Sure, this is not great comedy, but I find the idea of a toddler showing up at your doorstep and apologizing to you in full proper sentences for throwing potatoes at your cat to be amusing.
