After Christmas Tom and Harry were at work talking about what they bought thier wives for Christmas.

Tom says "I got my wife a 3 carat diamond ring and a brand new BMW".

Harry asked "if you got her a 3 carat diamond ring then why did you get a BMW".

"So if she didn't like the ring I knew that she would like the BMW" said Tom, "well what did you get your wife?"

Harry replies "well I got her a pair of flip flops and a dildo".

Tom laughs and askes "why did you get her a dildo?"

"Well so if she didn't like the flip flops she could go screw herself"
