Who’ll spark the longer line tomorrow morning: David Chang’s hamburger or Hillary Clinton? The First Lady turned Senator turned Secretary of State (turned President?) is signing her new book, Hard Choices, at the Barnes & Noble in Union Square tomorrow at 11 a.m., and chances are pretty good there’ll be a line of James Franco proportions when the wristbands are handed out at 8 a.m. (you’ll have to buy a book to get one, and no, Hillary won’t sign your Benghazi bumper sticker.)

If chilling with Hil sounds like too much of a hassle or she’s just way too conservative for you, here’s another politician to meet: Jón Gnarr, the zany mayor of Reykjavík, will discuss his new memoir, Gnarr!: How I Became the Mayor of a Large City in Iceland and Changed the World, at The Strand on June 19.

If you’ve seen Gnarr, the great documentary about the comedian and punk rocker’s bid for mayor in 2009, then you know his Best Party’s campaign was on par with the greats: Pigasus the Yippie pig for President! Hunter S. Thompson for Sheriff! an East Village nudist for Prez! Like theirs, Gnarr’s platform called for absurd things like a polar bear for the Reykjavík zoo and a Disneyland in the Vatnsmýri area, but unlike them he actually won, and went on to win the admiration of Lady Gaga by cross-dressing in Reykjavík’s Gay Pride parade.

Reykjavík elected a new mayor last month, which means Gnarr is free to speak frankly (not that he didn’t before) about his unlikely political career. To attend the 7 p.m. chat with Gawker’s Hamilton Nolan, you’ll have to buy a copy of the book or a $15 Strand gift card.
