I have many processes as well, but the top 2 are
The 'what if' cases, take any situation, any idea, anything really! And add an what if...? Of course the whats and the ifs have to be something that puts the event in a sarcastic, funny, humorous position.
The 'put yourself in their shoes' point of view. For example if you are writing about politicians, dumb people, highly hyper people, etc etc. Put yourself in their situation, most of the time i actually end up playing as the character like pretending to be George Bush or Bin Laden myself and things start to roll out by itself. If you were george bush what would you do to embarrass yourself? If you were Laden what are you going to do in your hide and seek games?
Learn from internet marketers (i consider myself one) - if they can get people to 'pay' in order to watch a 'fake bin ladens' death video, then i believe us writers can do better. The elements of Shock, surprise and excitement always work.
To be honest most comic writers are just too busy writing dark, intelligent or deep comedy. But lets face the reality, the future generations are not getting any smarter and the oldies arn't going to last forever. Take the example of failblog, collegehumor, break, smosh, theonion, etc. All these have modern day comic elements and not some 19th century deep humor, this is why they are successful. Don't write for your fellow writers (as most people try to do, its one thing to improve writing but its a different story when it comes to making a career out of it), write for the readers. Your readers are the generations of today. It doesn't matter how great your writing is, but can you sell it? Can you shock someone when they read it? Go take a look at those sites i mentioned and you will know what people like these days.
Good luck
