"Yo Soy Fiesta" has pretty much become Rob Gronkowski's calling card, and I can't help but love him for it. And that one-off joke -- it was an answer to a reporter's question in Spanish -- turned into a running joke, and perhaps a meme.
For instance, here's Gronkowski showing up to practice in a Yo Soy Fiesta shirt. Also of note: Logan Mankins, y'all!
This is the greatest Super Bowl practice photo.
