Sketch is one of the mainstays of British comedy. It is also the entry point to the comedy industry for most writers - you're more likely to get commissioned to write a 3 minute sketch than you are a 30 minute sitcom pilot. Whatever you're aiming to write, knowing how to craft a good sketch is essential.
