Is Seth McFarlane funny?

Many people absolutely adore the television show known as Family Guy. Personally, I don't understand it: the jokes seem to be utterly random and possess no real punchlines. South Park had a great example:

• "Peter, did you do the laundry?"
• "No, but let's not forget my date to Mexico with Gary Coleman!

...Um, what? Did I just hear that correctly? Because I thought this show was supposed to be comedic. Of course I am referring to Family Guy, as South Park is quite hilarious, if a tad foul. If someone enjoys McFarlane's work, then I won't hold it against them. I just don't see the appeal.

Yet in a recent trailer review for Seth McFarlane's new movie Ted, which to me looks like a similar strain for comedic attention, which it somehow receives, the YouTube comments absolutely blew a fuse when the reviewer said it didn't look good, and claimed that "no one can match up to Seth's bad-ass jokes" and that "anyone who doesn't like [his works] has no sense of humor." The sad thing is, many people are of this rigid closed-mindedness and similar forms of it, and yet a good deal of them are far less vicious in person, when there's no computer screen behind which they may hide as they type trollish spam to other users. In addition to that, it would be a miracle if more than an eighth of them passed basic English classes. It still makes me cringe when people type things like "im gud, u?" If they're in a rush, that's one thing, but people now use text language all the time just out of laziness and stupidity. One of my biggest pet peeves is when a person writes the possessive pronoun "your" in the place of the contraction of "you are" - in other words, I want to add an apostrophe and an "e" along with "an idiot." "You're an idiot." And I have Mr. Nantz to thank for that example, although I was no stranger to the urge then either. But this seems to have become a grammatical tangent. My main point is still that people have a right to opinions, and while I do not always respect the opinions, I generally try to respect the person.
