* DeaderThanDisco: Averted. While modern comedians frequently trash-talk the series (in particular, Creator/RickyGervais has gone on record as saying that this series showcases everything wrong with the classic BritCom format), it still remains very fondly remembered by most people.
* EnsembleDarkhorse: Lt. Gruber , largely for his countless HoYay moments with Rene and for being the most [[TheCutie adorable]] "nazi" in fiction.
* FauxSymbolism: Maria or René implies Gruber isn't interested in her but what they brought: and they pull out the sausage...
* HilariousInHindsight: Womanizing René is usually appalled whenever he sees that Lt. Gruber is hitting on him. In the mid 80's Gorden Kaye admitted that he is, in fact, homosexual. (And Guy Siner is not).
* HoYay: Gruber towards René.
** Occasionally, some of the other Wehrmacht soldiers towards Gruber, particularly when he plays the piano.
* WeirdAlEffect: The series was conceived not as a comedy about LaResistance but as a parody of British dramas about them, specifically the BBC's 1977-79 ''Series/SecretArmy'', which was popular enough to have its own sequel, ''Kessler''. However, ''Secret Army'' ran for only three series and has been largely forgotten, whereas ''Allo Allo'' lasted for ten years.
* TheWoobie: Von Smallhausen and ''especially'' Lt. Gruber despite them being Nazis too.
* {{Woolseyism}}: In Sweden, the show was called '''Emliga Armén'' ("Lame Army"), a pun/French-accented pronunciation of ''Hemliga Armén'' (the Swedish translation of ''Series/SecretArmy'').
