The Art and Ettiquette (did i spell that right??) of: "That's What She Said!"

Ladies and Gentlemen, Boys and Girls. I now invite you to read what everyone at school should know: The art of making "that's what she said" not only funny, but also making YOU look like something a little more than a hapless assface. First- and i stress this to you more than anything- the phrase of discussion CAN be used- just NOT as often as we use it. We tend to say this anytime anyone says ANYTHING!!! It is not appropriate to yell "T W S S" when someone says, "I love to use pencils." Second- The only time you can ever say "T W S S" in class is when: either, your teacher is not listening or hard of hearing, or, your teacher is young/cool and does not give a crap. Sometimes the teacher thinks the joke is aimed at them, and it may get you deeper in trouble than you think. Third- Only when the phrase used is going to make it EXTREMELY funny, may you say "T W S S." okay, this is bringing me back to # 1. If it is not worth while, don't do it. Now you have completed my short tutorial, and i believe there is now better knowledge of the do's and don't's of "T W S S."
