Adam is riding his new bike. A police officer on a horse comes up and asks him if Santa Clause got him that bike for Xmas. Adam answers:'Yes
', the officer says: 'Tell him to get you one with lights on the back next time'. 'Ok', says Adam.
Then he asks the officer if he got his horse from Santa Clause. He says: 'Yes, sure.' Adam answers: 'Tell him to get you one with an arsehole on the back and not on the top next time.'
