Sitting have a lazy late breakfast, sun is shining and this comes up, great start to the day. Showed my wife and she had the great idea that we should watch Fr. Ted from the start again. Fr. Ted first came out when I was in college in the 90s, Thursday night was the big night out for students and as new episodes of Fr Ted would air at 9pm our night out would start in a jammed pub with everyone watching it on a big screen. On a side note, not sure if this would be a sacrilegious or an ecumenical matter but having voice options for Ted, Dougal, Fr Jack, Mrs Doyle, Bishop Brennan, Fr Noel Furlong, Fr Stone, Fr Fintan Stack, Tom, Henry Sellers. That's just off the top of my head, there are many more.It was such magnificent writing and acting that characters that only appeared in one episode would still be mentioned as a joke or reference among my generation. Fond fond memories.
I remember when we were preparing to have our first kid 10 years ago we bought a monitor with the pad underthe mattress on the advice of other parents. As a former cpr instructor I was dumbfounded when I realised that parents would spend 100s on monitors but not one person had bothered to learn infant cpr.
