Naruto resisted the urge, he really did.
But in the end, the lure was just too great.
He ran past Hashirama, slapping him on the shoulder, yelling, "Tag, you're it!"
Sasuke stared at him in obvious consternation. "…What."
Naruto shrugged, a little embarrassed. "You know… Hash tag?"
"I don't know you."
From behind, they heard Madara yell out in anger as Hashirama's voice rang loud and true. "Tag, you're it, Madara!"
Sasuke just put his face in his hands and despaired.
