Is Rob Gronkowski immature? Yes, and that is why we adore him for being the 6’6″, 265-pound man-child that he is. Part of Gronk’s persona is being a gigantic NFL star with fame and fortune, yet having the sense of humor as that of an 8th grader. It’s kind of like Tom Hanks in the movie “Big,” but in real life.
That lovable youthfulness includes jokes about the number 69.Gronk doesn’t like the number 69.
Gronk LOVES the number 69!!!
