Irish Virginity Test Kit
Paddy was about to get married and asked his doctor how he could tell if his bride was a virgin.
The doctor said, ‘Well, you need three things from a hardware store, A can of red paint, a can of blue paint… And a shovel.’
Paddy asked, ‘And what do I do with these, doc?’
The doctor replied, ‘Before the wedding night, you paint one of your balls red and the other ball blue.
If she looks at them and says, "That’s the strangest pair of balls I ever saw", you smack her with the shovel.’
