Big Sean and Fallon proved they were great competitors as Fallon drew "when pigs fly," and Big Sean guessed it with flying colors. They even hugged after to celebrate that victory.
Their competition appeared weak when LL Cool J failed to draw a tattoo on an arm, but endless laughter ensued.

The show was not all laughs for Big Sean though. He got emotional during the show as he dedicated his performance of "One Man Can Change the World" to his late grandmother, Mildred V. Leonard.
"She was a female black captain in World War II. She was one of the first female cops in Detroit on the streets. She got her Masters at U of M. She was a teacher, a counselor. She was just the best grandma in the world," he said. "If anybody showed me one man can change the world, one man can change the world, man meaning guy or female, it's her."
