Tim Duncan's epic reaction to ref's call (GIF)

It was during the first half of Game 1 of the 2014 NBA Finals between the San Antonio Spurs and Miami Heat when Tim Duncan's emotion made a rare and epic appearance. 

The usually stoic 38-year-old was whistled for a foul in the second quarter and he did not seem to understand how the official could have seen any infraction.

Here is a closer look at Duncan's incredulous expression that referee Mark Davis might see a more times over the next couple of weeks.

The sight of coaches impeding with the course of play seems to be the trend these days (i.e. Jason Kidd, Mike Tomlin).

Now, watch as Kevin McHale tries to get in the way of a Tim Duncan inbounds pass in the Rockets' win over the Spurs Saturday night.

To say the least, Gregg Popovich was not amused.

Why the San Antonio Spurs are the coolest team ever

You have to wonder why the San Antonio Spurs— the most dominant team in the NBA over the last decade or so— still have fans wondering how their "Happy Days" persona still intimidates opposing teams more like Fonzie's 'aaaayy' than varsity nerd Potsie's 'Hey Mr. C.'

Tim Duncan seems more like Richie Cunningham or even Mrs. C during his NBA career  and head coach Greg Popovitch laid back more like Ralph Malph at the team's playoff game against the Los Angeles Clippers during half-time while staring at a 10-point deficit.

Pops still sets the standard for every NBA coach during his low-key tenure and, even during the Spurs' deficit at half-time, before his team turned into greasers in the comeback victory

The coach, Parker and Duncan sat side-by-side and looked totally keen with the way the Clippers had been running over them and — in a way— knew they were done for.  Call it 'Jumping the Shark' if the fish was a 24-point comeback.

Tony Parker said it all about his coach's half time moment.

We have "confidence: and there's "no panic."

It's hard to root against the Spurs, no matter where you're from.
