Quite the running theme isn't it: 1. Rimmer and Howard both competing for their fathers attention and lying about their careers (Trojan) 2. Lister's relationship with himself as his own father and not wanting to take his fatherly advice. (F&S) 3. Jesus not wanting to be his father's (God's) son and rebelling against his Dad's commandments (Lemons). 4. Lister wondering whether he has fathered a child back on Earth (Dear Dave) 5. Lister's ability to father children put in jeopardy via the groinal exploder - okay this one's a bit tenuous! (Entangled) 6. Rimmer's relationship with his father and discovering the true identity of his father! (The Beginning) And of course the series marks two members of the Naylor family being involved in its production: Notably Father and Son!!! What a weird coincidence!
