There are many wrong stories about the origin of yodel, like e.g. in the song 'That's how the Yodel was born' and I shall therefore now tell you the real story how it was born:

Two Japanese tourists were walking through the Swiss Alps. They had a little Sony radio with them playing music. When they crossed a glacier the one of them carrying the radio let loose and the radio fell down in a deep crevasse, but could still be heard playing down below. The other guy turned to the culprit and cried as loud as he could:
Holdoodiladio.
That's how the yodel was born.

O.K. I admit it's only for the select few like Joe and Ferrara (Bill!) and perhaps Ebbie and Alex. And the others? Well, just think it is one of these Gaelic messages floating through the threads.
