It's something I could never do again once i started stuttering the next day again.  It was the first time I felt such a placebo effect to that extent.  It was back in high school if I remember correctly because I'm pretty sure I worked at the place I picked it up at that night in high school.  But it was an interesting lesson that there was likely nothing special about any particular word, that the issue was something else.  That's one of the things I took from it anyway.
