Corrected entry: Many episodes of Dangermouse begin with the announcer describing Dangermouse's HQ as "a secret pillar box in Mayfair, W1". But what we see on the fence behind the pillar box is a sign saying "BAKER STREET". Baker Street is not in Mayfair, W1 - it is in Marylebone, NW1.

Suggested correction: That's his identical twin brother Pendragon, hired by DM so people won't think he had abandoned his trusty sidekick to the dastardly Baron Greenback.
Beware of Mexicans Delivering Milk - S6-E15
Penfold: Ah, good morning milkman, I'm just going to do my exercises.
El Loco: Ah si, you run, eh, you swim, you jump.
Penfold: No I lift the milk bottles.
El Loco: Guantanamera gringo.
Penfold: Er, no thanks, but we want some on Saturdays.
El Loco: If Saturday ever comes, eh?
Penfold: Erm, pardon?
El Loco: No importa! Hasta la vista!
Penfold: No just my pyjamas! Cor you can always tell whether they've been to Majorca for their hols. He even looks like that vicious Mexican bandit El Loco.
Trivia: Nero, the pet "hairy caterpillar creature" of Baron Greenback speaks in a strange gibberish. In fact this 'gibberish' is a recording of David Jason (who also provided the voice of Dangermouse, amongst others) albeit it speeded up and played backwards.
Correction: Obviously a security measure. You wouldn't expect them to broadcast Danger Mouse's real address, would you?
