Two folks whom I like seem to enjoy curling (the sport, not their hair). What the world could really use is a DVD that has two or three rounds of curling with a running commentary track by a fan. To avoid copyright issues, it should be a non-televised match by good teams. The commentary would be along the lines of "he did this because of that rule" or "she's doing this because of that common strategy". That would be sufficient to let the viewer know in about an hour whether or not they want to get into curling.
In Pilgrim terms, this is basically "learning about a sport for morons" instead of the way most DVDs and sports sites teach it, which would be "learning about a sport for assholes".
