It's PGA Championship weekend ... which means we're all dying to know one thing -- who's going to win?! WHO FARTED NEAR A HOT MIC ON THE BROADCAST?!?!?
Cameras and audio equipment appeared to pick up someone blowing the butt trumpet during the final hours of the 1st round of the prestigious tournament in South Carolina on Thursday ... and it's got everyone wondering, was that really a fart??
Check out the clip ... it sure sounds like someone broke wind all over the broadcast as Cam Smith was wrapping up his last putts on the course.
