Grace's
visiting
mom,
Bobbi
Adler,
a
would-be
star
whose
propensity
for
breaking
out
into
show
tunes
and
impressions
dismays
her
daughter
-
and
delights
Will,
Jack
and
Karen
-
wreaks
havoc
by
suggesting
Will
and
Grace
wed,
despite
their
sexual
differences.
When
Will
winces
at
the
fantasy
of
committing
to
anyone
who
needs
to
be
the
star
of
a
relationship,
Grace
realizes
she's
more
of
a
chip
off
the
old
block
than
she
imagined.
