Ok you received some critic already, but really this is possibly the worst way to create a comic. There are jagged edges everywhere, bodies, limbs and heads are changing sizes and proportion from panel to panel, the joke itself is not very funny and also to long drawn out and the text is overlapping the stickmen. Even if you decide to draw stickmen, you should try to put some effort into them.
Most things have already been mentioned by other users, but apart from that, I'm pretty sure this would look heaps better if you created the comics with pen and paper rather than on your computer.
Sorry that I'm so harsh, but I think there is no more polite way to say this.
At least some of your other comics are somewhat funny. So I think if you work on the drawing, it could be good.
