Shoddy, but has potential
Even if this was just made to flame some newgrounds member, it did go a little beyond that, which is good.
Unfortunately, it went on way too long and while the animation style did convey "insanity" it was also pretty crappy, probably due to it being made very quickly.
You could have cut out most of the parents dialogue (which wasn't funny and just boring) and gone right from turning the tv off to his foamy hallucination.
If you are going to make a short that has the express purpose of flaming someone else, quality is important, so that it doesn't get thrown back in your face. I have no problem with insult comedy, but it does have to be funny and well executed if you want it to be respected, even by its target.
