I just posted a comment on a blog, and the computer that deals with these matters immediately replied with a friendly message which began with the word 'Howdy'.
I don't know about you, but for me this triggered a silver wave of nostalgia. The Lone Ranger, Roy Rogers, Hopalong Cassidy ... They all said 'howdy' to heroes and villains, before shooting (never fatally) or embracing (never erotically) them. I suspect and fear that remakes or reworkings of these fifties classics are in some perverted Hollywood production pipeline, probably funded by an offshoot of News Corp. You heard it here first. They're already doing 'Dallas'.
I digress. What really interests me is: how many variations of 'Howdy' can you come up with, within the context? I can think of several, but wouldn't wish to spoil your fun.
