Math teacher: okay if you need an pencil than I need your shoe.
Students: our shoes?
Math teacher: no I only need one
Student: but why?
Math teacher: last year I gave students pencils and they never gave it back at the end of the class. So I take your shoe so u get your shoe back and I get my pencil back. If I take your shoe than you will remember to give me back my pencil because you want your shoe back.
Student: what if their feet stinks?
Math teacher: than I hope they have a pencil. By the way you can't use pens either
AUTHORS NOTE
UMM, is this bad that this is a true story.... This is why I always bring my own pencils to school. I need my shoe.
