DVC appears (dissed?) on Boston Legal

My best reconstruction from 3 minutes ago (without TiVo)

Alan Shore (lawyer) to gorgeous brunette in bikini at the day spa: What are you reading?

GBiB, holding a hardback book up so cover is easily read: The Da Vinci Code

Shore: Are you enjoying it?

GBiB: It's OK. Have you read it?

Shore: No. It's enough for me that DaVinci was a brilliant painter and engineer, without turning him into the Karl Rove of the 16th Century.
