Chalk

i was standing at the front of the class one day, "write on the board." my teacher said. i picked up the chalk, and began to talk, and would write what came to my head. "123, ABC" i wrote, under pressure, trying not to choke... cause when I turned around, to speak to my crowd, my teacher said "What is this, some kind of joke?" i reversed my last motion, standing dazed and confused, i yelled "This was not my intention!" i looked at the chalk, as it began to talk, saying "face it, you're gonna get some detention!" "Mr. Adams is Stupid!" is all that was there, in plain sight, for all to see. i picked up the eraser, to delete this foul mark, when chalk stated "Don't bother, he's working with me!"
