For the record, I created this
this answering machine message well over 10 years ago on my Macintosh IIsi, sticking a microphone up to my Betamax recordings of Star Trek:TNG and editing the file in Soundedit.
It now seems to be floating around the net in various places, though someone cut out the "shut up Wesley" part I had in there. Somewhere around here there is Star Trek:TOS version as well.
I used this on my answering machine for about a month. It confused the hell out of people and even my friends would just hang up. I
think it was because of the message.
Link to a transcript as well.
