Puffer was promoted to Boston on September 2, 2004, and was in the Red Sox bullpen that night but did not pitch. He was designated for assignment the next day by the Red Sox in order to clear a roster spot for outfielder Adam Hyzdu. Boston ultimately won the World Series championship that fall, and team owner John W. Henry decided championship rings would be given to any player that was on the Red Sox roster that year. Despite never having thrown a single pitch for the team, Puffer received a World Series ring. The 18-carat white gold ring was encrusted with diamonds and adorned with a ruby "B". It was featured on an episode of "Pawn Stars" (season 8, episode 61), but was not sold because cast member Corey Harrison was concerned of Puffer's reputation.
