Stuttering on purpose

Stuttering on purpose Today I started stuttering on purpose while ordering food to desensitize myself to the fear of stuttering, but I started laughing!! “C-c-c-c can I gggget a mmmmeatbbballl sub” I just couldn’t hold it together. Honestly, most of it was probably just nervous laugh. It was more uncomfortable than it was funny. I’d say I made a little progress. I’m gonna try again some other time and try to keep it together. Anyone else ever try stuttering on purpose?
