Did anyone notice the old high school student?

It's Becca's 1st day at school, and while she's walking down the hallway, a large man in dungarees, tshirt & unbuttoned flannel over shirt is walking down the hall in the background and when he turns to go in a classroom, you can see the gray hair on his temples. He turns enough to see the gray hair on each side. It surprised me as a subtle joke as the movies in this genre consisted of blatant jokes
