Being a twin comes with a unique set of challenges, but it also has several benefits. For NBA brothers Marcus and Markieff Morris, that benefit came in the form of cheating on a middle school exam, according to a report from The Athletic.

Markieff, who now plays for the Washington Wizards, was apparently better at math in those days. Marcus, now with the Celtics, was the superior reader. Knowing this, the brothers decided to try their hand at a swap, and it worked.

“He took a math test and then I took his reading test because he was just better,” Marcus tells The Athletic. “He was better at the subject. And then we switched back at lunch time.”

In what proved to be a fitting twist, the Morris twins were selected with the 13th and 14th picks in the 2011 NBA Draft. Both have developed into fine players since then.

Marcus has become a key member of Boston's rotation. He's made 25 appearances with the Celtics this season (eight starts), racking up averages of 14.4 points on 49.0 percent shooting from the field (42.9 percent from beyond the arc), 6.2 rebounds and 1.5 assists in 26.7 minutes per outing.

Markieff, who is seven minutes older than his twin brother, is enjoying a fine season with the Wizards. He's played in 26 games for Washington (15 starts), averaging 11.6 points on 43.5 percent shooting (34.5 percent from downtown), 5.3 rebounds, 1.8 assists and just under one steal (0.8) in 26.2 minutes per contest.

Like most siblings in their youth, the Morris twins got in fights when they were growing up. Markieff tells NBC Sports that the bickering stopped when they were about 12 or 13 years old. Since then, they have been inseparable. The two attended the same college (Kansas) and began their NBA careers together with the Phoenix Suns, where they went on to become the first brothers to start alongside each other on the same team.
