I'm an outsider in all of this but am enjoying the thread. I heard about a chap who had a deformed leg, causing him to rock from side to side when he walked. He was known as "The Sniper's Nightmare".
A good mate of mine is called Richard and is a cardiologist. He's known as Dicky Ticker. Another chum who frequents this forum has the surname Ware. One wag started calling him "Tupper".
