Vijay Singh and Paul Tesori
At the 2000 Presidents Cup, during a match with Woods, Tesori caddied for Singh and wore a hat that read "Tiger Who?" Singh never uttered the phrase, but like a presidential candidate, he approved the message.

"I don't know where he got that hat," Singh said at the time, "but I said, 'Why not?'"

After Tiger defeated Singh, 2 and 1, he was asked about the question on the back of Tesori's hat. Woods responded, "He knows the answer."
