eBay - dabbers at the ready!

Whilst searching eBay for all things bingo I had a brainwave - a change to the original version of the joke about blonde's and PC's....you know the one, "How do you know a blonde has been using the pc? There is tippex on your monitor!"

Well my version is "How can you tell when a blonde has been playing online bingo? - There are bingo dabber marks on the monitor!"

Ok, so it isn't the funniest joke in the world, but it made me chuckle! Sad isn't it that I laugh at my own jokes.
