A possible reference to The Grinch Who Stole Christmas by Dr. Seuss
in which Roast Beast was the traditional Christmas
dinner of the Whos. The phrase has become a popular playful way to refer
to roast beef.
Buffy: I'm trying to put this all behind me
and I'm not going to be able to as long as we're doing guest
spots in each other's dreams.
Normally a guest spot is a star appearing
on a talk show or a musician appearing on the album of another musician.
Of course normally people don't dream together.
Oz: And you got the Barry
working for you.
Barry White who can be heard playing in
the background is the epitome of the love making music.
