Already known for his lack of emotion, Jason Dufner recently took things to a new level.
In a story from Deadspin that quickly made the rounds Thursday, a picture of Dufner shows the two-time PGA Tour winner staring straight ahead with less facial expression than even he customarily portrays.
According to the report, Dufner was appearing at the Salesmanship Youth and Family Centers, a Dallas-based charity that works with at-risk youth and teens, as part of a kickoff luncheon for the HP Byron Nelson Championship, an event he won a year ago.
Dufner missed just his second cut of the season at the Arnold Palmer Invitational last week, and will next head to the Masters in two weeks, still in search of his first top-10 finish on the PGA Tour in 2013.
Later, players took to Twitter to display their own versions of what's been dubbed #Dufnering. View those images here.
