Your contributions are slipping a bit there Jude, although maybe it's just your mind that's going.
Curling was a demonstration sport in the 1988 and 1992 games, and became an official medal sport in 1998. It was also in the 1924 and 1934 Olympics, so it is possible that your grandpapy was in one of those, but somehow I doubt it as your post was likely just a feeble attempt at humour, eh.

The funny thing is that pool is not in any way an Olympic sport

, and they are both games that you can play while drinking and smoking and telling dirty jokes !

League: World Curling Tour (WCT)
It's hard to believe that one can make any kind of a living sliding a large puck on ice then chasing after it with a broom. Believe it.
Like tennis, curling has its own Grand Slam, comprised of four major events: the BDO Curling Classic, the M&M Meat Shops Masters of Curling, the Canadian Open of Curling, and the PharmAssist Players Championship. Each of these tournaments offers a purse of $100,000 Canadian (roughly $83,000), except the PharmAssist Championship, which offers $150,000 Canadian ($125,000).
Kevin Martin is the current leader on this season's earnings list, having pulled in more than $85,000. In the 2004 TSN Skins Game alone, his team's winnings topped $75,000. As of January 2005, the median winnings among the World Curling Tour's top 10 earners was about $55,000.

Pool is not a top paying professional sport, and neither is curling, and neither is squash, and neither is darts, and I hope you get the idea.
