Paddy is planning to marry but he has one worry. How can he tell if his bride to be is a virgin? He seeks advice from a noted sage who tells him:

All good Irish men use just 3 things, as a kind of D I Y Virginity Test Kit, a can of red paint, a can of blue paint and a shovel.

And tell me now said Paddy, what am I supposed to do with these 3 things? Well, said the wise man, before you climb into bed on your wedding night, you paint one of your balls red and the other blue. And if your new bride says: "Well, that's the strangest pair of balls I ever did see..... you hit her with the shovel"!
