Paddy The Greek was an unseen character in Only Fools And Horses and was a friend of Derek "Del Boy" Trotter. He was a man who sold Del a lot of the dodgy gear Del sold down the markets. He was never seen in the series but mentioned throughout.
Paddy The Greek (real name unknown, maybe Patrick) was a friend of Derek "Del Boy" Trotter and probably went to school with him. Paddy became friends with Sunglasses Ron and Monkey Harris. Like Del's friend Trigger, they stole things from warehouses to sell to Del and other traders.
Paddy The Greek sold Del Boy many hookie items over the years, including stealing some lead from the church roof in 1986 so Del Boy could pull off a scam to raise money for a local hospice. Paddy got Sunglasses Ron to help.
