I have a brother with Tourette's syndrome. He had/has no verbal tics, but does have physical ones, as well as noises he makes. His main noise these days is whistling, which sounds very similar to the whistles of the family's pet parakeets. The parakeets all adore him (not that surprising, I guess...)!

I, too, thought from the title of the thread that it would be about Tourette's or Coprolalia,)
