David Proval did an exellent job,playing Richie.The guy really got under Tony's skin.I couln't stand the guy,but in his own way,he still had some manners.Ralph Cifaretto instead,was a disrespectful jerk,the way he talked to Spatafore,at the hospital,when his brother was in a coma,or how he talked to Gigi,after he was made capo,was enough reason to shoot him right away
