strange thing can happen!

at the risk of being rude, what about bogeys?

PS I can't believe I'm 34 years old and have said that word...

It's never too late.

I actually fouled a player, because the hair on his arm touched a ball.

I knew a Judge like you once, sent me down for 3 months for riding a bike without lights.

Gawd knows what he'd done had I been riding it at night.

...and what happens if some moisture from the players breath should condense on a ball in play????

Could a pedantic ref insist on swabbing and DNA testing every ball after every stroke???

or what if while leaning over the table he disturbs some dust sitting on top of the cushion rail, and some of said dust wafts about in the air currents and before settling on a ball??? How can the player prove that he did not bring the dust to the table?

I did say technically.
Wity - but it is 'equipment' referring to a players clothing! And Yes, the rule does imply snooker equipment, but the original question did refer to a 'button' and hence my reply (and others).
Enough said on this topic?
