During the wrap party that followed the taping of the final episode, Ardal O'Hanlon's father, a general practitioner, expressed concern about Dermot Morgan. He noticed that he appeared very unwell, and told him to see his doctor as soon as possible. Less than 24 hours later, Morgan suffered a massive and fatal heart attack.
After the broadcast of the first episode, the network received just two complaints: one criticizing it for being too anti-Catholic Church, and the other criticizing it for being too pro-Catholic Church.
Introduced the word "feck" to the English language. It was already common in Irish English. Vernacular usage of feck in the expletive sense is syntactically interchangeable with "fuck", though it has no sexual connotations and is actually closer to the word "damn".
Dermot Morgan announced that he was leaving the series and that Series 3 was to be his last, because he wanted to move on and do other roles.
