Carefully. :) You want to be sure to discharge the
high voltage first (in both the terminal, and whatever
you're stealing a tube from!). To do this, attach a
length of wire to the metal shaft of a flat blade
screwdriver, and ground the wire to the chassis of the
terminal/whatever. Hold the insulated plastic handle
of the screwdriver and slide it under the rubber
suction cup of the picture tube, until you feel the
metal clip inside. Typically, this will be accompanied
by a *CRACK* as the high voltage discharges.
(Although, it is possible that the HV dissapated
earlier, depends on the terminal) Do this twice just
to be sure.

* Be careful messing with high voltage stuff! Keep
one
hand behind your back when discharging tubes, and be
sure your discharge tool is properly grounded to the
metal chassis of the device. There's several kV
potentially stored in there. I don't believe there's
enough in a terminal to kill you, but it'll hurt like
hell. Best to be as careful as you can.
To this I'll add: Don't assume that once you've discharged the HV that it
will stay that way! I've been bit by that one before...
