While looking for information on the physical specifications of the gahoon, I ran across mention of the Maui Xaphoon and of the Maui Xaphoon Pocket Sax. Now, a pocket saxophone could be a good thing, but the marketing by Maui Xaphoon indicates how it could become a social ill:

It will bring you JOY — Imagine being able to create a sense of community wherever you are — at a bus stop, in a cave, waiting in line, even a parking garage!

Yeah, imagine. Imagine innocent people stuck at the bus stop, spelunking in the Sand Cave, queued at the DMV, or just trying to get to or from their cars, and some g_dd_mn'd would-be pied piper tries to horn them into a community to end the loneliness of his here-to-fore friendless existence.

(BTW, if you don't want to pay US$57.95 or more for a pocket saxophone, then consider flubberjibbel's DIY pocket saxophone. Just don't try to rope me into some community with it.)

Up-Date (2020:09/25): The Maui Xaphoon products pages have moved, and the lowest list price of a The Maui Xaphoon Pocket Sax is now $65. (The DIY video to which I linked parenthetically was made private, but a search of YouTube finds other videos for DIY pocket saxophones.)
