I had about 13 Irish lads working on a job I was supervising a few years ago.
One of them thought it would be funny to wear a rag shirt one day to see how I would react.
Next thing you know, he was shirtless and his shirt was on fire in the back garden.
Not before I removed the badge so that I could chuck it in the urinal at the pub and film myself pissing on it for him to watch at the bar.
To be fair, he was a good sport about it.
