My brother has a moustash,too, but he never mentioned getting it stuck in his harmonica though.

It was funny just yesterday, I was playing around on my harmonica, thinking about that fly story, and saying to myself: surely there isnt a fly in this one, no chance. I turned it upside down and rapped it on the table.

A tiny, fuzzy, WORM fell out. :o(

not kidding either... Cheers, Dixie
