After 10 O'clock

Setting: the apartment, getting ready to go to bed

Me: I've heard really good things about Moneyball! I didn't know it was written, or at least the book was written, by Michael Lewis.
Josh: Michael Lewis? Really!
Me: Yeah! And did you know he is married to Tabitha Soren? Do you know who that is?
Josh: Of the Soren Foundation*?
Me: Did you just say that?
Josh: I don't know what I'm saying.
Me: No, Tabitha Soren of the mid-90s MTV News.
Josh: Oh, don't listen to anything I say after 10pm.

* I have Googled and this does not come up with anything. He was really making things up.
