Years back I took a cruise to the Bahamas, to the islands of Nassau and Freeport.  On the latter of those, they were selling these giant conch shells for $5.  (In the U.S., you can order one online for like $45.  Yeah, I know - Why would you do that?)

I was himmin' & hawin' about buying a souvenir, as buying crap adds up fast, and I'm very frugal.  Then, this awesome salesman at the shop demonstrated how to use... yes, use... this shell... Much like I do here:

OKAY, okay, I'm not the best at it, but you get the idea.  I was never a great clarinet player either, but just so you know, you form your mouth on the shell the same way you do on a clarinet or saxophone:  pinch your lips tightly together and kind of smile - so it looks like you're trying to keep yourself from laughing (and you may be.)  Then, pump some wind into that baby!  Kids love it!  Dogs - well, they react.  And, it's a great conversation starter when you have company.
