As many have said...
Great drawing and animation, top notch shit. However, perhaps a bit more writing could have been done before making this flash, because it did lack there. I really wanted to like a lot of it, and some of it got a chuckle out of me, but it wasn't quite right. As for anyone saying it's not "adult humor," it's true that it isn't all that vulgar or anything, but it really doesn't need to be so. Sure, a little bit more vulgarity might entertain people, and I could see it working out, but I'll just be disappointed if I end up seeing a cock every other sketch (a typical Newgrounds flash, unfortunately). The voice acting was great too, by the way.
Again, it was good, and I got a few laughs out of it, but... and I don't mean to single out PresidentZen, yet the writing isn't quite on par with the art. On the other hand, I'm sure you can improve it.
The dinosaur sketch... meh. I could MAYBE see that working, but it might have been funnier if he was a bit more erratic by the end, and the dinosaur in the background sort of lacked context (was it meant to be a presentation the guy was showing? a sort of thought bubble? a separate illustration entirely? Could have switched to a scene of him getting worked up about some modern atrocity or something, maybe even something ridiculous; regardless, he seemed outraged at humanity for nothing in particular, as I said before, context).
The fridge sketch was alright, but for whatever reason it didn't work for me, I really don't know quite why. :/.
The bee hive sketch could have zoomed into something a bit more dramatic, specific, and/or extended. For example, you could have zoomed in and seen the queen's mate (I know they technically have many mates and what not, but bear with me here) in his final seconds, looking up at the queen as he coughs and dramatically dies. I did like the general idea, though.
The dog detective one was quite funny, yet almost out of place in that no other sketches had the same type of humor. Perhaps a sort of related sketch with a dog in a formerly serious situation could help.
The Satan - God one was simple, but one of my favorites.
The bear sketches were pretty funny too, yet maybe the remains of the previous characters could have been a bit more apparent (I found myself unsure about the drawings on the grass, though that's more drawing related.) Of course, after going back once, the remains were obvious, but the sketches were a little too quick for me to be sure of them the first time around.
As for as the sand box one: it was alright. The blood coming out of his ear was a nice touch, but it too lacked context. I'm assuming he built the baseballs into the sand castle cause he got brain damage from the previous baseballs, but it was a little unclear. Maybe, for the third cut, he could have been wearing his helmet, building the castle normally (no baseballs, no brain damage, but still the blackeye). A baseball could be thrown really hard into the frame, cracking the helmet and knocking him over. The kid would be laying face down, then, after a few moments, lift himself up with a ridiculous look on his face. He'd ponder for a moment, look at the baseball, hesitate, and then place it onto the castle, and then make those brain damaged sounds.
I really did like the idea, and I'm not sure how much Flecko contributed to the writing, but it really could use some work. Sorry for the wall of text (I don't mean to come across as condescending. I'd never be able to make something this good.). The reason I've gone so far into the details (especially with that sandbox one) is because the flash is so close to being amazing, but not quite there, and I'd really love to see an improved sequel.
