Gronk's eyebrow raise every time Josina says 69 are incredible. Jumping out of his skin he wants to laugh so bad pic.twitter.com/XQRJWREOTj — Feitelberg (@FeitsBarstool) December 14, 2015

This is the most self control Rob Gronkowski will every display on camera. Why? Look what happens when he hears ESPN's Josina Anderson say the number 69 -- twice. Gronk's inner turmoil is almost too much to bear. He wants to say "nice," he wants to scream it from the top of a mountain for all to hear -- but instead he kept himself calm and collected. A simple eyebrow raise to let the world know what he was thinking.

Gronk is probably watching this video today and shouting "NICE!" at the top of his lungs -- simply for the catharsis.
