Character mistake: During the scene of the dinner, James (Raquel's father) states that he was in the Royal Navy and was "First Officer" (1/O). The Navy does not have this rank since it is a Merchant Navy rank. The rough equivalent of this is Lieutenant in the RN and Albert would've known this but didn't mention anything. It is also extremely unlikely that an officer the RN would still be Lieutenant after doing his full quota of 12 years service.
Character mistake: No referee in wrestling would allow a double team to occur without either trying to break it up or counting to five. Yet here he allows The Golden Girls to do so twice.
