Trigger (Only Fools and Horses) point of the silliest joke, such as in "Fatal Extraction", when Del jokes with Boycie, Mike, Denzil and Trigger, saying that women ask men something then correct them, and everyone says "Why ask" together, and Trigger waits until they're finished and says "Why ask?" very stupidly. In the pilot episode Rodney asked Del where Trigger got his nickname, thinking Trigger was an armed criminal (i.e. a trigger man). Del, however, replies that 'it's because he looks like a horse', this is a reference to the famous screen horse, Trigger of the 1950s and 1960s, as Del says to Trig later
Grandad (Only Fools and Horses) Albert fell out over Albert's later wife, Ada. Albert tells Rodney that while walking home from a nightclub together, they both had a fight, and never spoke to each other again after that. The character of Grandad was written out of the original show following the death of the actor Lennard Pearce but is featured heavily as a main character (called frequently by his real name "Ted") in the 2010-2011 prequel series "Rock & Chips". Set in 1960, we see Grandad recently separated from his wife Vi, unemployed and subsequently homeless, after she finds out about his affair with Alice.
