(Hmmm - perhaps when the Beginnings DVDs get up to Jason's arrival in Ep #193, we should start a running count on the forum to see just how often Dennis Patrick points with his finger, just as we did with how ofter RD touched his hair.
Which reminds me - I want to post a new topic on Current Talk about keeping a lookup for a certain something while watching the Beginnings DVDs...)
