JFK was called "Lancer" and Lady Lacqueline was called "Lace".... That one is just too easy, kind of like Dog's sister.
Speaking of which, time to start nominating.
For Robocop I would suggest we call him "Shadow"
Canebrake gets to be "Gelding" - Because he sure isn't getting "Colt"
bkt - Professor. Easy call
Davyboy - Hmmm, I don't have a clever name for Davy. Everything that comes to mind is too British and easy.
