How do your friends react to your stutter?

How do your friends react to your stutter? A lot of the time my friends wait for me to finish (which is very helpful) but when I prolong the 'S' (usually at the start) one of them will go "Kaboom" like the "sssss"' was a bomb. Playing off my stutter like that as a joke helps me not feel ashamed for it and my friends are great at it.
