Speaking of the Well, does anyone know the latest on Captain Crunch?
Did he get out of that counterfeit BART ticket pinch and get his gear
back?  Or is he breaking rocks on some island somewhere?

Yeah, but you can't do that on videotape.  Stuff just comes out too much
to the right on everybodies TVs.  I guess no one knows what 'centered'
means in NTSC, I never got any response there.

Yeah, I have to agree, your little hacks have been the most fun of anything
I've seen out there.  I was over at a friends house a couple of weeks ago,
going through my PD disks to see if he wanted any of the latest net utilities
etc. and he saw 'robotroff' on a disk.  "What's robotroff do" he said, and I
just kinda said "oh, nothin' much" and quickly changed the subject.  Later,
I slipped robotroff onto his main boot disk when he wasn't looking (put it
in the :s directory, named it 'date' and put it in his startup-sequence as
:s/date).  It was real late, and he never rebooted that night after I
left.  I heard about it two days later when he called up with a message on
my answering machine "alwright Doyle!, what the hell are these little aliens
doing with my pointer!".  He had looked around for something fishy on his
boot disk, but naming it 'date' completely fooled him.  "You wanted to know
what robotroff did!" I said.  Lotsa laughs.  Thanx again Leo.
