My Dad's a vicar so not many expletive filled rants for me but phrases and moments that have stuck with me are:-
The time he tried to 'get' hiphop and ended up saying in a bewildered way…
"It's like the withdrawal method for sex, just when it gets to the good bit you pull out and it starts again how frustrating"
On my borrowing any of his expensive carpentry tools "Take it and use it, but don't abuse it and go on your way rejoicing"
The time he walked into the lounge and I was watching the French film La Haine. It being French he thought his son was going to be watching some art house ponce fest and when confronted by a subtitled tirade of swear words…
"Don't they French know how to write poetry anymore?".
Top fave is the time he tried to convince me that a long time platonic female friend was good wife material and I should get rid/over the girl I had been seeing for three years. I explained that the friend also had a boyfriend she had been seeing for three years.
"Sometimes other people get it wrong too"-
not exactly a howler, but two years later when I went back for Christmas the friend got hammered and tried to seduce me explaining that she'd held a candle for me for years, so there you go sometime's Dad does know best.
