Anagrams
On the noticeboard in my form room, we used to have this slogan stuck up saying something apparently motivating about wisdom and community and hard work and a couple of days ago we all came into the classroom and someone had rearranged it to say DEA IS BUTTOCS and I WANT A TIT WANK. It was awesome.
Except Ms. Stevenson came in this morning and made us all rearrange it to spell out the original... only now no one can remember what is used to even say. XDD
Now instead it just says I OWN DIS TING.
