Cover the headphones up with a pillow! Play decieving messages into the
microphone port! Start up a NeXT version of those 1-900 services, and play
inviting messages (while recording your clients responses, no less!)!
Who knows? Maybe the resonant frequency of the NeXT is such that all speech
is translated into Antarctican...and then uuencoded!
Good point, nonetheless.
