At about minute 8:30 in the episode, Red is talking to an old friend in rehab. He mentions that step 9 in recovery is about making amends. This is a reference to Spader's Seinfeld character who was in a 12 step program. Spader's character would not apologize for ridiculing George for trying to borrow a cashmere sweater, saying his head would have stretched out the neck hole.
