The club has several hazing rituals, such as requiring the most junior relief pitcher on the team to carry water and snacks to the bullpen in a brightly colored small child's backpack (Barbie in 2005, SpongeBob SquarePants in 2006, Hello Kitty in 2007, Disney Princess and Tinkerbell in 2009, Chewbacca and Darth Vader in 2010), and many of its players, both past and present, are notorious pranksters. For example, Bert Blyleven earned the nickname "The Frying Dutchman" for his ability to pull the "hotfoot" – which entails crawling under the bench in the dugout and lighting a teammate's shoelaces on fire.
