Know your audience. You will not be able to produce the same type of satire for a church as you would your coworkers, and you should be aware of the limitations you may face because of the type of audience you are courting.
Decide what your topic will be. Satire is often a persuasive argument in disguise, like a Trojan Horse of thought. Figure out what you want to say, what you feel needs to be changed or addressed.
Create your cast. For instance if you have decided to make a political statement, you can use politicians and pundits much like the long-running "Saturday Night Live" did through its "Weekend Update." Celebrities also make recognizable targets, notably used in the satirical Pink song "Stupid Girls." For something more personal you can even use yourself and those you personally know.
Use parody. Other television shows that successfully produce satire often parody easily recognizable pop culture icons. This includes "Family Guy," whose opening sequence parodies the classic television show "All in the Family."
Use irony. "The Cobert Report," a Comedy Central channel program, satirizes serious news programs by offering news which uses verbal irony to say one thing, but really mean another. In this case, ridiculous statements are delivered with rather arrogant authority to subtly poke fun at anyone who might actually believe it.
Take things beyond where they have previously gone. Good satire is unafraid to push the limits, and risks being ridiculous and outlandish, such as "The Onion."
