escalator got the last word

are you smarter than a fifth grader? I cannot even outthink a road grader. I am not a professor or super market demonstrator. Are you smarter than a fifth grader? I doubt I can put cheese on a cracker, said McFrator. I am dumber than you are, said his sister, Mater. I do not even understand how to peel a tomater. This tickled our friend, Samuel McFrator. Are you smarter than a fifth grader? They asked of a passing escalator. The escalator got persnickety said Crater. She stuck up her nose and walked off with Slater. Slater is a friend who is way dumber than a fifth grader. He once lost a chess contest with a road grader. We are losers said McFrator, Crater, Slater and Mater. The escalator yelled “You are all dumber than a fifth grader!”
