Stuttering and acting

The question came up on whether it is true that stuttering does not happen while acting.  Here is my take:

Stuttering is situational, and different situations affect us differently, but I think it is clear that words that come from memory and with a rhythm (as in singing and poetry) are processed differently in the brain, and in ways that, for most of us, "bypass" the areas that are vulnerable to stuttering. It's probably similar for acting, where lines and associated rhythms are memorized. I did do some acting, and I had this experience: my initial rehearsals, when I was using memorized lines, were free of stutter, but, as I "became the character" my stutter crept in again. I was amused when the director started noticing it and "liked my choice" of making the character a stutterer!
