Jake Bullet

When Kryten gets a bit too into bragging about how Jake Bullet of the Cybernautics unit must be, Rimmer brings him back to earth by pointing out, for all they know, Cybernautics could simply handle traffic control and Bullet just happens to have "a rather stupid macho name". When confronted by the secret policeman, Kryten tries to talk his way out of it by flashing his badge and announcing himself as Bullet from Cybernautics. He's promptly informed that Cybernautics handles traffic control.
