Colin Arthur Ball, better known as Trigger,[1] is a fictional character in the BBC sitcom Only Fools and Horses and its prequel Rock & Chips.

A regular at the Nag's Head pub, and old friend of Del Boy, Trigger is a road sweeper - looking after a 20 year-old broom that is an example of the Ship of Theseus paradox - and also engages in trading and petty thefts.

The 2015 official "autobiography" of Del Boy, He Who Dares, states of Trigger: "It was generally agreed though that his dad was Donald Turpin (brother of Mum's best mate, Reenie)... when Elsie started showing, she claimed she'd been 'visited by an angel!

But Donald had been heard bragging about how he'd lost his virginity... giving full details of the time and place, and was therefore fingered as a much more likely suspect than the Archangel Gabriel.

The script was subsequently rewritten to omit his role, although it is mentioned in the sketch that Trigger cannot assist Del and Rodney with their latest business venture because he is working at the market.
