John Cena released this public service announcement through the Ad Council today, and you may find yourself blaming all that July 4th barbecue smoke for the patriotic tear you'll be shedding. It's the most stirring appeal to our better angels by a musclebound hero since 1949 Superman taught kids about what it means to be American.

Cena may be a massive guy who hits people with metal chairs for a living, but he's also well-known for being a total mensch; among other things, he holds the all-time record for wishes granted at the Make-A-Wish Foundation. Take a walk with him down this beautiful typical American Main Street, and by the end he'll have you wanting to hug your fellow citizen hard enough that they might have to tap out.
