Every giant viral ad needs a parody (or a few dozen), and so Bud Light is here with a spoof of the American Greetings "World's Toughest Job" video—celebrating dads instead of moms.
The joke writing is a little odd—it's caught between wanting to honor dads and wanting to make fun of them, and doesn't really accomplish either one very well.
The gold standard for this kind of parody was the spoof of Dove's "Real Beauty Sketches" where the guys suffer from excess self-esteem rather than the lack of it. That came from a comedy group, though, not from a brand with a vested interest in not making guys look too buffoon-like.
