1) the school's quarterly newsletter, which had just been distributed
2) a pen or a pencil

Me : Children, find Miss Suhaila in the newsletter!
Kids : Yeayyyyyy!
Kid 1 : Miss Suhaila, how many Miss Suhailas must we find?
Me : (scrutinising very quickly) Um, five. There are FIVE Miss Suhailas!

After a while, the children came up with the following:

Kids : Teacher, there are only four Miss Suhailas..
Me : No, there are five. Look again carefully.

A few seconds later..

Kid 2 : I found all already!!

Kecoh siak.
