Well, first of all, the element of surprise is crucial. Let's say you thought you were going to a normal family dinner but it turned into a wild costume party. Then, having relatable characters, which is often you or people around you. If you describe their quirks and reactions in a humorous way, it makes the story better. And don't forget about the comical timing. Pausing at the right moment or speeding up the story can add to the hilarity.
One key element is self - deprecation. For example, if you can laugh at your own mistakes or clumsy actions, like when you tripped over your own feet in public. Another is unexpected situations. Such as going to a wrong place but having an amazing adventure there. Also, the way you tell the story matters. Using vivid language and funny voices can make it more engaging.
