I agree that you have some potential. The situations you've provided are humorous, but you don't seem clear about how to make it funny to the reader.
The first thing to do is to get rid of the narration. It's redundant, distracting, and generally a sign that you don't know what the hell you're doing. Second, know when to end the joke. The "Dude, you're insane!" line in "The King Has Returned To Claim His Throne," for example, is completely unnecessary. The joke's already been told. More emphasis doesn't help; readers will expect there to be another joke if the dialog continues.
In summary: You don't have to fill out all the fields in every comic. You've got some good ideas, you just need to learn how to better turn them into comics.
