My favourite was one I spontaneously started myself on the last train into Sheffield in the mid-90s.
I was alone and a bit the worse for wear and urgently needed a piss so I sauntered down an empty carriage towards the toilets when I met 5 scumbags sat in the last seats just before the toilet.
As I passed them head down one of them lashed out at me with a kick and as I scarpered into the toilet another one followed up with a comment infering that I was in for a kicking when I emerged.
In the temporarily safety of the toilet my alcohol-addled brain reckoned on taking a 50-50 punt (absolute carnage vs chance of safety) with a song so as I came out of the toilet I roared at them aggressively "YOU FILL UP MY SENSES, LIKE A GALL.."
... There was a very brief silence whilst this new information was processed
... and then a loud roar whilst my new scumbag pals broke into "Na Na Na Na he's a Blade and ..."
(Or, thinking back all these years later, maybe I was so fuckin hard that they were Wednesdayites who shit themselves??
