Drew Lynch, stuttering comedian, with an interesting story
 

He was on America's Got Talent and almost won (I didn't know that until I saw the TedX video).

He stutters a lot, but is still pretty darn funny.

Funny, far less stuttering (older and less anxious)

That was very cool... thanks for posting it :)!

Crazy that he fell while playing softball and woke up with a severe stutter.

I think he was hit in the neck by a ball. Damaged some nerves. The stuttering started after that.

Yeah, I saw/heard him say that in a video, I think the AGT video. But in the Ted talk, he made it sound like it was due to the concussion (hit in the throat by a softball, and then fell back and hit his head). So those two videos left me unsure if it was due to the hit in the throat or the concussion (which both happened within seconds of each other). And now there are times when he almost has no stutter at all. (like the Ted talk).
