During an August, 2006 game an ESPN shot revealed that Granderson had written the words "Don't Think, Have Fun" on the underbill of his cap.
After visiting London in the off-season, Granderson is now a British baseball favorite, with Britain's Channel 5 baseball show MLB on Five now including a segment called "Granderson Watch", taking over from Weaver Watch (after Jeff Weaver got a World Series ring). The segment involves Curtis answering weekly emails and occasionally appearing live over the phone.
According to a Detroit Free Press article one of Curtis Granderson's hobbies is spending a lot of his spare time on the internet. Curtis says one of his favorite sites is [www.youtube.com].
Curtis Granderson (0-for-13), Ivan Rodriguez (0-for-11), and Placido Polanco (0-for-10) were the first group of three teammates, each with 10-or-more at-bats, to go hitless through the first three games of a World Series.
As of November 2007, more Facebook users have named Graderson as their Tiger in the Who's Your Tiger application than any other player.
Granderson often has 1990's West Coast Rap played as entrance music for each at-bat at Comerica Park. This includes "Bad Intentions" & "Nuthin' But A G' Thang" by Dr. Dre or "2 of Amerikaz Most Wanted" by 2 Pac & Snoop Dogg. He has also used tracks from Outkast and N.E.R.D..
