Confidence is the most important factor when you need to make anyone laugh. It is the basic tool required to perform any duty, so never be shy of saying something, but make sure you don’t hurt others.
Command on your subject
You will feel much better when you have total command on your subject. If you know what to say, then there will be no pressure on you.
Understand the crowd
You will never get one type of crowd everywhere, so it is important to assess what type of people are listening to you. Once you have made the assessment, only then you should crack some jokes as per their liking.
Show respect to everyone in the audience
Never disrespect someone in the audience. If you show respect to others, they will do the same.
Learn a few good jokes
Learn a few good jokes and write them down, so that you don’t forget them. However, make sure that you present them in your own style. And that style should be good.
