When Lennard Pearce died in 1984, writer John Sullivan chose not to replace him but to write the character 's death into the series. A funeral was held for Grandad in "Strained Relations '', which saw the Trotter brothers trying to come to terms with the loss of a man who had been such an integral part of their lives. However, such was the nature of the show that amongst the sadness were moments of brilliant comedy. At the funeral, Del sees what he thinks is Grandad 's trademark hat, takes it to the grave and he and Rodney lovingly drop the hat in. It is later revealed (to the audience) that the hat actually belonged to the Vicar. As Del and Rodney walk away from the grave, the gravediggers begin to fill in the grave; Del turns to them and menacingly says "Oi! Gently. '' This episode also introduced Grandad 's younger brother Uncle Albert. It is also known that apart from Albert, Grandad had two more brothers: George, whom he mentioned in the episode "The Russians Are Coming ''; and Jack, who was mentioned by Albert in "A Royal Flush '', presumably the father of Del and Rodney 's cousin Stan, who is seen at the funeral with his wife (Stan refers to George by his first name, making it improbable for Stan to be George 's son).
