Clint Eastwood
Jumped in front of him while he was playing golf
When I was about 10 years old my older brother and I followed Clint Eastwood around Torrey Pines golf course in San Diego, CA during the Andy Williams open pro-am trying to get his autograph. After several holes without getting his attention I ducked under the ropes and ran in front of him as he prepared to tee off. He laughed good naturedly and signed my book.
