What are good ways of generating nonsense, absurdity and silliness?

I know there are some of you out there. So many seem to want to be mostly serious or if they desire fun, to have it in a serious way. Are there any jellies who appreciate absurdity, nonsense and silliness? I just love taking things from a serious starting point, and running off into the wilderness with it. Sometimes it annoys the hell out of people. What fun!

I’m curious about how to make it happen. How do you get people to allow themselves to be fools? Not care about how they sound? Just play?
