One tip, frodo. When choosing a name for your main character, make it something short and simple enough for your own attention span, so as to avoid getting bored with it and having to resort to referring to said character only by its initials.
Actually I thought the first one was great. The implied joke works very well. You should write more like that. I read all the others and didn't like any of them. My advice is don't do series. Too often you find yourself writing pointless, humorless comics just to advance the plot, or else writing comics that have nothing to do with the plot just for the sake of getting a joke in there somehow.
