I may be able to help you. What is the purpose of your speech?

You want to give an entertaining speech. An idea is to think of three or four places or situations funny events happen, for example work, school, in the house, on a bus etc and then think of one or two examples for each. So in the house you might think about pets or cooking or the toilet! It might help if you can show some pictures.

Can you talk about more than one event?

well, I have to talk about funny everyday events, but it's really difficult to think about an specific situation and talk about that one for more than 7 minutes.
