It's swell

Rating: Null/10 (29 April 2002)

Ebert says about Mulholland Drive: "One of the scenes also contains the funniest example of pure logic in the history of sex scenes." Can someone tell me what he's referring to? I can't think of what it could be. Thanks in advance. (PS--I liked this movie very much. My poor, struggling left brain is trying to piece every little bit together but my grooving right brain loves it as it is.)
