Everyone knows this.
But the jokester met his match on the table at the WGC-HSBC Champions, falling to PGA Tour rookie Zecheng "Marty" Dou in what looked like an intense match.
Dou, 20, became the first Chinese-born golfer to earn his PGA Tour card earlier this year. Unfortunately for him, Kuchar got him back on the course this week.
Through three rounds, Kuchar is 7 under while Dou is 6 over.
