 Floppy Edition (Script 69, craniumTalker)
 {{{
         (method (dispose param1)
                 (if (or (not argc) param1)
                         (craniumThumbs dispose:)
                         (craniumBrow dispose:)
                 )
                 (super dispose: param1)
         )
 }}}


 CD Edition (Script 69, craniumTalker)
 {{{
         (method (dispose param1)
                 (if
                         (and
                                 (or (not argc) param1)
                                 (or
                                         (not (proc0_4 147))
                                         (and global194 (!= (global194
 talker?) self))
                                 )
                         )
                         (craniumThumbs dispose:)
                         (craniumBrow dispose:)
                 )
                 (super dispose: param1)
         )
 }}}
 Debugger command "vv g 194" says global194 is craniumTeller, whose talker
 attribute points to craniumTalker. If I'm reading this right, the CD
 edition seems to be sparing craniumThumbs from disposal?

 The lab is script 370. It declares craniumTeller, whose cue() hides
 itself. And it declares delayMsg, whose changestate() method starts the
 ''protection'' puzzle (script 88) and calls showAgain().
