Bosco & why grandma said it

    I was just catching up on the past few days' posts, when I saw a short
thread about why J. Peterman's grandmother says "Bosco," just before she
dies.  Although I certainly realize that it refers to George's PIN code,
was I the only one that also saw it as an allusion to "Citizen Kane" and
ROSEBUD?  We've discussed previously in this ng the many allusions to
movies the show makes; I saw this as yet another one.
    Agree? Disagree?
