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.
