In our world today, the only definition of a crazy person is someone who is too 'out there' to be able to make a living. Really, when you sum it up, that's the bottom line. If robin Williams was not a comedian? He would have been homeless. If Seinfeld didn’t have a stage to make millions on, he would be the obnoxious kid living with his folks until they die.
Seth is the perfect example for it. It is not that he is not talented. He is very talented, fiendishly t alented, and in so many crosssections of the creative field. But if we take a look at American Dad, and Family guy, it is obvious that without the poetic license of these shows? He would still be a thirty year old who gets wedgies and does shadow puppetry in his parents basement…
I wouldn’t say seth's sense of humor is weird. This would be like saying the ocean is 'damp'. Seth manages to take a weird sense of humor, drag it on the floor until it crosses each and every line of good taste, add a bucketful of pure violence, sprinkle some disgusting smut on it, and then arrange it in a brodway golden stairs , feathered dancers ultra gay musical. And it works. It works. It works.
