Funny Humor
A big part of getting someone to laugh is that you need to have funny humor and this can be achieved a few ways. The best way is to get really good at the timing and presentation of the article that you are presenting. You want to say a punch line that is totally unexpected as it will be passed of as no even worth remembering. Sometimes the best humor is the most obvious thing yet totally unexpected as you delivered the leading question in a way that got the other person questioning what they would normally say like, "What do you call a cow with no legs?", "Ground Beef" hehe.
