Before setting a world record in the 200m at the world track championships in Berlin, Usain Bolt echoed John F. Kennedy with a handwritten message on his Jamaican training jersey:

That's simply fantastic.

Kennedy's famous Cold War quote delivered near the Berlin Wall was "Ich bin ein Berliner" which meant "I am a citizen of Berlin." Bolt's shirt refers to Berlino, the official mascot of the IAAF World Championships in Athletics. Translated, Bolt's shirt says "I am a Berlino". It's not quite Kennedy, but this may do wonders for athlete-mascot relations for years to come. 

Berlino has been quite chummy with the athletes at the championships. He can be seen celebrating with most of the victors after their events and even gave a piggyback ride to Jamaica's Melanie Walker after her win in the 400m hurdles. (It ended abruptly after Berlino ran directly into a truck carrying hurdles.)

Bolt and the mascot staged a mock race after Bolt's dominating victory in the 200m, with Berlino pulling out a narrow victory. It's the only race Bolt has lost in a long while.
