Yep, I posted the same topic last year. I heard Vigoda on a sports-talk show (Tony Bruno, I believe) claiming he said the line. Old Abe must be having memory problems b/c that is positively Clemenza's voice. The novel has Hagen say it.
DC, I'm not picking on you b/c you are not the only one who does it on these boards. But since your post had it misspelled under the topic heading, I want to point out that you spell the word D-E-F-I-N-I-T-E-L-Y. Thank you, I feel better now.
