Words you can keep
A fascinating but, unfortunately it seems, moribund form of radio broadcasting that utilizes radio frequencies from about 1,800 kHz to 30,000 kHz. Some say that the Internet is totally to blame for shortwave's demise, but in fact there are many other reasons: poor propagation conditions (e.g. coronal flares on the Sun that can block radio reception for many days), mismanagement and bad frequency allocation by the stations themselves, transmitters in disrepair, lack of funding for the stations, radio frequency interference caused by various appliances that create walls of noise when one is listening for stations, etc. On shortwave, one can often hear interesting cultural programs and music produced by the host country, and some shortwave listeners have created a hobby-within-a-hobby of collecting "QSL" (verification of reception) cards, pennants, CDs, books, etc.
Back in the late 1970's, I loved to listen to Radio Tahiti on my shortwave receiver.

The Great Moroccan Kleenex Shortage of 08-09 

In March of 2008 the demand for Kleenex's in Morocco increased at an unbelievable rate. The Moroccan King asked for everyone to stay calm. He attributed the increase in demand for Kleenex to Peace Corps volunteers spending too much time in their masterbatorium, spanktuary, spank schack, whack shack, jack shack, flip n jack, finger hut, spank cave, spank wagon, cumgeon, cum station, lunch punch, stroke boat, spank bank, corner of crank, jerk hut, masturbation station, spankmobile, homostead, spank shed, and master barriums. In particular, undercover sources attibute the increase to one "King of Crank" J-Lub (known for exceptional stroking form.) When asked for comment, J-Lub simply said "whatever dude, I'm gonna go listen to some music." The King has told people to hold strong. The King also claimed that supplies are expected to return to normal around the time of Tallstacks 2010.
Oh man, I shouldn't have ate all that spicy couscous. Now I can't blow my nose due to The Great Moroccan Kleenex Shortage of 08-09

endwarfins

The rush of neurotransmitters and neuropeptides triggered specifically by watching the Seven Dwarfs march home singing "Heigh-Ho" — that particular high of pickaxes, whistling while you work, and communal domestic bliss in a cottage built for men half your height.
I only meant to watch the Heigh-Ho scene for the endwarfins, and then it was two hours later and I'd watched the whole movie.

Endwarfins aren't just a Snow White thing — I get the same hit off the Lollipop Guild in Oz.
