Disclosing in a comedic way

Disclosing in a comedic way The topic of self disclosing can be controversial and I might be adding a bit more scandal to it. I prefer to self disclose, primarily before interviews or public speaking situations, because it makes me feel better that the people I'm talking to are prepared for it and don't think I am having a stroke. I have a speech coming up later today and I've been racking my brain on how to self disclose in a comedic way to ease the tension for myself. I figure adding a joke that isn't so self disparaging but lightens the mood would work. Has anyone tried this or had success with it?
