I got my handle a long time ago. I used to be into running, street races. One time I entered a race with a different format, no prizes for being first or second........ This race you had to predict your time, closest person would win. Well 3 days before this race I had broken broken 40 minutes in the 10k for the first time, a personal best. So I predicted a pretty ambitious time for this one, it was only 5 miles so I figured I would do even better. Well anyway I had the worst race of my life and finished 10 minutes after the time I predicted. If that wasn't bad enough, this particular race gave a prize for the person who was farthest off the time they had predicted. The prize was a huge polish sausage for the one they called "THE BIG DOG", guess who got the prize? I have a whole room full of trophys I won running, but this is the prize I am always reminded of. When I got into playing pool later on I had a problem with choking on the nine ball, my dad would tell me " you were the big dog then and you still are now!
Thats how I got my handle.
