As one of the more unique creative professions, comedians are essentially on there own. Outside of an audience and a microphone, there are no real tools that you need to do this job. You simply need to be able to take an idea and convey it in a funny way, which itself requires you to understand WHY something is funny in the first place. You will often work in comedy clubs and other public places in front of large groups of people, which will require you to be very comfortable on stage. In comedy, you're not really collaborating with anyone outside of your own brain so you need to be comfortable working on your own.
