I got two
My aul man was MC'ing a race night in the local (oo aar) and I was drinking guinness all night at 17, on the way out to the jacks I puked about 3 litres of stuff in the corridor. There was no way around it and about 20 people saw me do it. I'll never forget the look of disgust I got from him between races

Kept drinking though
The other time was when my mates aul man started taxi driving. His first night he picked us up to bring us home after copius amounts of beverage, he drove over a humpback bridge and from the backseat I plastered the windscreen and the radio.
He doesn't like me
