I pulled out 28D ” _, James _”: BOND because as Calah and I have been going through the Bond movies in order, we saw one where James Bond went under the pseudonym James Stock. I found that to be very funny, especially as said by Roger Moore. Still my opinion is that Pierce Brosnan is the worst James Bond. Sean Connery is the best.
