Over the years, J.R. Smith's capacity as a role model has been questioned. In 2006, he tackled Nate Robinson into the stands. In 2009, he served 24 days in prison for a car accident he caused. Later that year, he closed his first Twitter account (@jr_smith1) after being accused of writing in a gang-like manner. In 2012, the NBA fined Smith $25,000 for posting a suggestive picture of model Tahiry Jose on Twitter. In 2012, Smith was arrested in Miami Beach, Fla. after missing a 2011 court date for operating a motor-scooter with no valid license. In the 2013 playoffs, Smith received a one-game suspension after elbowing the Celtics' Jason Terry in the face. During the Knicks' second-round series versus the Paces, a picture surfaced of Smith partying with Rihanna.

On Friday, the tables turned. J.R. Smith decided to play mentor.

Angered at the social media use of his "lil cousins," Smith (@TheREALJRSmith) took his feelings to his Twitter followers.

Sparks fly:

And you thought Smith was a reckless party animal? The 27-year-old, who made his NBA debut shortly after his 19th birthday, knows the delicacy of a teenager. He also knows the danger of drugs and alcohol. In November 2012, Smith attributed his hot start to the season to less partying. "I was going out pretty much every other night, just not focused on the task at hand. This year is definitely different," he said.

J.R. Smith won't let it go:

This is reminiscent of Allen Iverson's 2002 practice rant. Iverson repeated the word practice to emphasize his point. Smith wants his followers to read over his latest tweet about his cousins. He is clearly upset.

Details arise:

Whoa. It is unclear how many cousins are involved, but at least one cousin is a female. Smith thinks this kind of talk about smoking and drinking is not classy coming from a girl. He uses vulgarity to express his seriousness.

J.R. only cares about his life:

Maybe Smith is only a role model to his family, not all of his followers and fans. Smith argues other people can write what the please on Twitter. He only wants to influence his cousins' tweets. He capitalizes and quotes, "MY LIL COUSINS."

At this point, it appears 'cousins' is meant to be singular and there is only one cousin involved.

J.R.'s had enough:

Smith does not care if you follow him or want a retweet. He is focused on himself and does not care all that much about you. He curses again, this time at his followers, but he is nice enough to use asterisks.

George Carlin is rolling around in his grave. Smith should have used the asterisks for the previous curse, one of the "Seven Words You Can Never Say on Television."

J.R. is king:

Smith is making millions as the second scoring option on New York City's most historic basketball team. He is the breadwinner of his family. What he says goes. When Smith wants his cousin to stop talking about drinking and smoking on Twitter, the must abide by The Dude.

Smith takes a few minutes to regroup. He responds to some of the more light-hearted questions his followers ask him.

However, a tweet from Diane (@nyjetsgirl25) catches his eye.

The retweet:

No answer. Smith straight up retweets it.

All in a day's work for JR Smith, New York's newest health teacher.
