Ina Gebert, M.A (Theologist)
I'm pretty sure everyone has noticed this, but hasn't posted it.
This woman is Chuck's funniest friend that he always talks about. She was acknowledged in Fight Club, and she gives her own insight in the Rant book regarding liminal experiences and such.
And in the back under Contributors it says: Ina Gebert, M.A. (Theologist) is an asset at any party.
I thought that was pretty cool. A nice little "shout out" to one of his friends.
