Tiger Woods is known for pumping his fist. John Daly grips it and rips it. Back in the day, Chi-Chi Rodriguez danced and Arnold Palmer gave his signature wink to thousands of fans.
Golfers have long been known as characters, showing their emotions during the highs and lows of a hole, a round and a tournament.
Jason Dufner? He shows about as much emotion as a goldfish.
"His whole demeanor is very stoic," fellow PGA Tour pro Zach Johnson said. "I'm sure inside he is wrestling and fighting and that sort of thing, but he doesn't look like a typical grinder out here.
Never miss a local story.
"He just goes out there and hits it. He just kind of trots to it, sees the line. He plays that kind of golf. The club gets in the way, and that's great."
The even-keel approach has paid off for Dufner of late, and he's been more than happy to follow a script only Hollywood could produce.
Over a 22-day stretch, Dufner won his first PGA Tour event (Zurich Classic in New Orleans), got married and then won for a second time at the HP Byron Nelson Championship last week.
Asked about keeping his emotions in check, Dufner said: "Something really bad has to happen for me to kind of get a spike either way up or down, or something really good. It's just more of a personality thing than something I've worked on."
In fairness, Dufner can let his emotions fly when he's off the golf course. As an Auburn alum, he couldn't believe when Cam Newton led the Tigers back from a 24-point deficit to beat Alabama in the 2010 Iron Bowl.
"Usually there is some alcohol or Auburn football involved," Dufner said, smiling after his Nelson win.
Now, Dufner will look to become the first player since 2009 to win back-to-back weeks. Tiger Woods was the last to accomplish that feat, winning the Buick Open and the Bridgestone Invitational in consecutive weeks in 2009. Woods then went on to a second-place finish at the PGA Championship.
The last player not named Tiger to do it was Vijay Singh back in 2008 with victories at The Barclays and Deutsche Bank Championship.
"It's difficult to win one week in a row out here," Dufner said. "There are a lot of things that go into it that make it difficult. I think for me the best part will be on Thursday when I step up to the tee and actually start to play some golf and see where I'm at."
Even with his hot streak, it's hard to make Dufner a favorite this week. In three career appearances at the Colonial, he's missed the cut twice and finished tied for 59th in 2009.
Dufner, though, likes the layout of Colonial and feels it can suit his game. He has put together decent rounds, including a 7-under 65 in the third round in 2009.
"Never quite put it together for the week," Dufner said. "So maybe a little bit more experience on the golf course and building off last week. Maybe that will get me going through this week."
Getting on -- and staying on -- a hot streak is one of the most difficult things to do on the tour. Just ask Johnson.
Johnson had a notable six-week stretch in 2007 in which he won the Masters and AT&T Classic and finished sixth in the Verizon Heritage. Sometimes it doesn't work out that way.
When he won the Colonial in May 2010, Johnson didn't have another top-10 finish until August, when he came in a tie for third at the PGA Championship.
"It's very, very difficult," Johnson said. "What Dufner has done is obviously very impressive. I would think last week's win is correlated to the fact that he kind of knows how to win now. He got that proverbial monkey off his back. It looks to me like he is just letting it happen and that's pretty dangerous.
"It really doesn't surprise me and he is just feeding off of that momentum. It's fun to watch. Hopefully it's magnetic ... I shook his hand today."
