Safety First

A father and his 11 year old son walk into Boots The Chemist. The son sees some boxes of condoms and asks: "What are these dad?" The father answers truthfully: "These, my boy, are called condoms. Men use them to have safe sex." "Oh.. i see!” the boy answers.”They showed them to us at school, in a biology lesson which was a sex education class." Then the boy looks at a packet with 3 condoms in it and asks: "Why does this one have only 3 in it dad?" "This, son is for high school kids: One for Friday, one for Saturday and one for Sunday." Then the boy looks at another packet that has 6 inside. "What about this one? Why does it have 6 in?" "This is for college students: Two for Friday, two for Saturday and two for Sunday." Then the kid sees a packet with 12 inside and with great wonder asks: "And this one dad, with 12 inside?" His father sighs and explains to him: "These my boy, are for married people. One for January, one for February…"
