You know things are getting intense when public librarians start talking smack about the World Series.
In a series of back-and-forth tweets, the city librarians in San Francisco and Kansas City began taunting each other – with book titles, of course – over which team is going to win Game 1 of the World Series Tuesday, the Giants or the Royals.
"We're polite but fierce!" the San Francisco library tweeted. "Get ready to cry some blue tears for @Royals when @SFGiants take the win tonight."
Michelle Jeffers, the social media guru for the San Francisco library and the mastermind of the tweets, had an obvious answer for why she was dissing the Kansas City library 1,500 miles away.
"Well, they started it," she said with a laugh.
In fact, they did. At 11 a.m., the Kansas City Public Library, tweeted: "Hey @SFPublicLibrary we have a book for you!" The link showed this title: "So, You Think You Know Baseball? A Fan's Guide to the Offical Rules," by Peter E. Meltzer.
"What? They think we don't know the rules?" Jeffers joked.
Liesl Christman, the digital contest specialist at the Kansas City library, happily admitted to "starting it." And she said she chose the baseball rules book while flipping through the catalog, trying decide what bibliophile zinger to fling.
"Yeah, I was hoping to get a response," Christman said from Kansas City by phone. "I just didn't realize it was going to go on so long."
The Twitter tete-a-tete went on for so long, partly, because Jeffers wasn't going to take it lying down.
She shot back: "Thanks, but maybe you should read this." And she sent them a link to Dan Fost's book, "The Giants Baseball Experience: A Year-by-Year Chronicle from New York to San Francisco."
Kansas City took aim again, pointing out that the Giants haven't always been in San Francisco - the team was once a favorite in the Big Apple. Christman tweeted a stack of "fairy tale" books with the hashtag #TaketheCrown.
Jeffers fired off another dig, albeit a courteous one, simply stating that the Giants history has been amazing "coast to coast."
"I didn't want to diss them too bad," Jeffers said. "I was trying to be polite because we're librarians here."
