How can I make someone laugh?

You could always tell corny, classic jokes. They always make people laugh even if they have heard them a thousand times.

First of all ,be yourself. Forced humour is the worst in my opinion. If you're trying way too hard and not being yourself will sound fake. So be yourself and try to go with jokes that, to you, are funny, that suit your sense of humour and that you think people will enjoy it
