reading gets me going

i've just got 2 books!

"can cows walk down stairs?" by paul heiney
this is a very interesting book, or so i think. it provides explanation for very stupid questions like... why can't you tickle yourself? and why don't woodpeckers get headache?
i know these questions are weird and stupid, but seriously, do you know the answer?

also, i bought..

"the most enormous book of brainteasers ever!"
this book is not exactly very enormous i guess. it's only about 4.5cm thick. but it looks fun! that's beside the point. i bought this book not only for the sole purpose of keeping the idiotic kids in school occupied during lessons but also because i'm going army soon. according to some unknown sources, it is said that army makes one stupid. although it's not exactly verified, i still do not want to take the risk. so in order to prevent that, it's good to do some brainteasers every now and then to keep my brain working. (although i know i'll still end up looking at the answers for every question. hahs.)

anyway, today was a b o m b .
12 teachers were absent. (i told you teachers were lazy...)
guess how my timetable look like?
mind you, only 2 relief teachers were around.
HOW TO SQUEEZE 12 TIMETABLES INTO TWO?!
freaking hell...

what is the difference in the no. of days between friday and today? THREE.
