I found this in IMDB. (It’s kind of poorly written and confusing.) What was he thinking?
“Norman Mailer, in the director’s commentary on the DVD, said that he was counseled to cut the ending of the scene in which ‘Ryan O’Neal’ ‘s character Tim Madden reads a note from his ex-girlfriend Madeline informing him that his wife was having an affair with her husband in which he exclaims “Oh God! Oh Man! Oh God! Oh Man!” due to O’Neal’s poor performance. Mailer kept it in because he thought the poor line-reading actually added something to the picture. O’Neal, who had been friendly with Mailer, turned on him as the bit revealed his short-comings as an actor and embarrassed him.”

You’re right, that is really poorly written and confusing. Way to separate your thought with two miles of jibba-jabba!
