Using 'theeee' and 'ayyyy' as opposed to 'the' and 'a' to slowly lead up to a blocker and avoid it with a smooth 'run-up'. It must come across as though I'm thinking about what to say next. I believe this is engaging the right - singing - side of the brain. Other than that just not caring is best. Appreciate that you've not got something worse and embrace one of the things that makes you different to others. Wear it.
