Shirtless Pirates Fans are part of the #YESMovement

In the sixteenth inning of Tuesday night's Pirates game, these guys went a little...Buc wild (ba-dum-chh!) chanting, "Yes! Yes! Yes!" over and over.
Yup, Daniel Bryan of the WWE and last year's beard-off has finally inflitrated baseball. His signature victory chant is sneaking into sports chants everywhere. Instructions on how to join the #YESMovement:
1.Put your arms up in the air.
2. Squat.
3. Stand up.
4. Yell, "YES!"
5. Repeat.
