The fly story is reported in this Sports Illustrated article from 1955:
Vest-pocket Master Of Six-pocket Billiards
That was such a strange pool happening. The poor man commit suicide, all because a common house fly landed on his cueball, resulting in him missing a shot.
Here's a shot of Alex Pagulayan out in the hallway right after a defeat on a close pool match. He was still in the tournament, though, as he was not knocked out. He kind of looked dejected, so I asked him if he was okay, and he happily replied in his usual Alex style, "Oh, yeah, I'm fine. The only thing that hurts are these uncomfortable shoes. My feet are killing me." :grin:
