Counting Condoms – A boy goes to the drug store with his dad and sees the condom display. Boy: "Dad, why do they do packs of one condom?" Dad: "Those are for the high-schoolers for Friday nights." Boy: "So, why do they make packs of three?" Dad: "For the college guys for Friday, Saturday and Sunday nights." Boy: "Then why do they make packs of 12?" Dad: "Those are for married couples — you know, January, February, March."
