Castle Season 7 Episode 6 Rick ends up in an alternate universe where he's never met Beckett or anyone at the 12th. Can he convince them to let him help with the case so he can get back and marry Kate?
Beckett: (Clears throat) Ahem. What's the deal with men and boobs, anyway? Castle: Biological. We can't help it. Beckett: But doesn't it bother you that they're so obviously not real? Castle: (Pauses) Santa's not real. We still love opening his presents.
