Mouthpieces. Very High on the List of Things You Do NOT Want to Smell.

At least when they're dirty anyway. They're ok when they're new. I know this because I was just cleaning the mouthpeice on my beautiful saxophone Adolphe (named after Adolphe Sax, who invented the saxophone, not the Nazi leader). It was really nasty. Just thought you'd like to know if you don't already... DON'T SMELL WOODWIND MOUTHPEICES or old reeds. They don't smell so good either.

May the Force be with you, Adolphe (my saxophone.)
