It's no joke when a German man asks someone to pull his finger — it's a declaration of war. The traditional Fingerhakeln aka "pull my finger" championships took place recently in Garmisch-Partenkirchen, Germany. How does the competition work? Two opponents sit on a table and hook their middle fingers into a leather ribbon, before trying to pull each other over the table. Resistance to pain and finger flexibility are put to the test.
