The real question should be, "are those boobies man made?".
Absolutely not. She lost a bit of weight since her days on Community and naked always looks smaller than when you have a pushup bra on.
Having said that you get to see them in their glory twice in the first episode. Sadly, this isn't a trend for the rest of the series.
Still a recommended watch for it's offbeat and witty humour and cute triumph of the underdog story.
