...the Vuvuzela.
It's a brasswind made of plastic. But it seems to be more than just a f*cking loud tootle:

Well. At least I have a new word for Scrabble .

There just has to be an indoor, but not necessarily smaller or quieter, version available for hockey games! –– Go 'Hawks!!

Gets me to thinking about creating my own instrument of some sort. I thought I'd done it once with a hinged set of 2X4X8 inches wood. But nooooo....

I've taken my baritone to the occasional playoff game when my son was playing high school, junior and travel league hockey. Throwing aside the blanket and landing on a solid low A, tugboat-like blast cut through all of the clack bottles (plastic aquarium jewels inside of empty Poweraide bottles - very loud when shaken correctly) and air horns.

It is cumbersome, though...

[Old Dick]

I honestly can't imagine getting a horn into a game! Even us sedate, professorial looking types get patted down – e.g., at our St. Cloud State vs Minnesota games to make sure we aren't carrying dead gophers to toss on the ice whenever we score. [And what kind of a mascot is a stupid gopher, golden or otherwise, anyhow???] – I couldn't smuggle in a baritone even if it had its own ticket...

"I'm with the band" is a phrase that generally works .
