Aww, why not? I've had many an enjoyable evening with a spirited debate over the politics of lame internet slang jokes.
Mediocre artwork, not funny... Well, I got a grin out of the elephant. But, since I don't want to just be an ass, let's see... What I notice more than anything about the art is how bland it is. For the first strip, I think a side view would have been more appropriate than your failed attempt at perspective. But if you want to do it, try actually utilizing vanishing points and such when you draw. You'll get out of your comic what you put into it, and it really doesn't look like much has been put into it with these strips. The backgrounds in the WWII strip are more interesting, but altogether, it still displays the same overall blandness and lack of artistic care. Look around at other comic artists, see what they do, notice what exactly makes their comics interesting and desirable to read. Basically, work with what they do until you can put together something in your own style that still incorporates what you've learned from your observations. Good writing can overshadow poor artwork, but good artwork will make a comic that much more engaging.
As far as your writing goes, well, keep at it. Your dialogue isn't bad, but when you go for random, bizarre humor (like the fifth strip), it lacks the sort of punch necessary for a laugh... The most successful strip is the one with the elephant, because it sets up the joke (or rather, in this case, humorous situation), but doesn't reveal it until the last panel, and goes somewhere the reader probably didn't expect it to. But what you have to rely on above all else is whether or not YOU think a joke is funny. "Stop. Wasting. My. BANDWIDTH!" Did you laugh your ass off at that? I doubt it. And that's why nobody else is going to. And the whole "Oh noes! LOL!" kind of bit requires a lot more tact to be received well. Use it sparingly, though I'd personally avoid it entirely... Ultimately, you have to rely on your own sense of humor. Though what's funny to you may not be funny to someone else, your own reaction to an idea is a decent gauge for how others will react to it. If you have to ask if something is funny, there's a 99% chance that it isn't.
Most importantly, though, you'll have to decide where you're going with this strip. It looks as though you've got recurring characters in mind, but at the moment, they may as well be nobody. If you're planning to have any sort of story, they need to be developed, both in appearance and personality. But if you're going for a storyless comic (refer to the granddaddy of all character-less, storyless comics, Perry Bible Fellowship), really make an effort to divide the build-up from the punchline, and surprise the reader, since there generally will be no recurring situations to draw humor from.
Everything you've shown needs a lot of work, but it's promising enough that no one ought to discourage you from it. I suppose, though, if you're not prepared to put the necessary effort into it, you may as well give up now. But if this is something you really want to work at, do just that. Keep at it, and with any luck, it could develop into something good.
EDIT: Something to add... The real benefit to having an ongoing story, especially for those who aren't great at writing quick jokes, is that you can interest the reader in what's going to happen next, whether than if any given strip was particularly funny. Jeph's jokes aren't always that funny, but does this mean I would give him shit for it or stop reading? Absolutely not (well, maybe he gets shit for it sometimes, I dunno). QC's main strength is its appeal to our pathos. Its characters are well-established; we relate to them, and we want to know what happens to them. In your strips, none of this exists. There's no introduction, no development, no turn of events... If you want to have a story, really take the time to consider who your characters are, what drives them, where they're going, how they relate to each other... You want them to be real people - not just crude drawings. Of course, if you don't want a story, well... disregard all that.
