Any joke snooker-related (involving snooker or the players etc).
I don´t have one here, but to illustrate the point I come up with one "rugby joke":
The old Welsh rugby joke came to mind. A woman advertises for a mate, describing herself and claiming she had a spare ticket for the game against England at Cardiff. Interested man replies: “send photograph – of ticket.”https://www.express.co.uk/comment/expresscomment/639048/Lotto-jackpot-split-winner-David-Carol-Martin-Susanne-Hinte-laundry-laundered-ticket
In this case, a rugby joke because it was a ticket for a rugby match. The lad (the guy) didn´t ask for a photo of the lass (of the girl), but for a photo of the ticket!
