Anyone could do it

I have noticed that a lot of people feel slightly intimidated by the word "satire". Most people seem to agree that they are capable of understanding and using irony and sarcasm, while they regard satire as something that can only be used by professional comedians and writers. I see it as my job to tell you that this is not the case.  In fact, everyone who has ever felt annoyed at something and made fun of it in a way that exposed the stupidity of the said something has used satire in one way or another. Satire does not have to be political; its core lies in it being critical. As an example of this, one could look at this video clip by the Youtube channel Satire, which makes fun of Iphone 5 (i.e. not a very heavy subject): 

However, having said this, you still need to practice in order to be able to write good satire. More importantly, you have to conduct serious research/have real knowledge of what you want to satirize before you can truly satirize it. Jonathan Swift could never have written A Modest Proposal had he not been “exiled” to Ireland. Voltaire would never have written Candide if he had not been exposed to the inequalities of the class system in 18^th century France. In short, you are only capable of achieving great things with your satire if you are really knowledgeable and/or passionate about it. But if you find your passion, gain knowledge and start writing I say you have a pretty good chance of coming up with something great. Satire was made for the masses.
