Call Guinness Book. At least I’ve not read about an older streaker. As reported in the Irish Independent:
Police in Duisburg, Germany are becoming rather irked with a serial streaker.
They hauled him into court after he streaked during a girls’ football match. But they were rather surprised when, during the adjournment the man removed his clothes again.
It appears he views himself as a living work of art. Given that he is 60, it’s presumably abstract art.
(My sources tell me that the man received funding from President Bush’s abstinence program.)
