Given the following context: Mr. Dinkle and Jack (Abbott and Costello) look for work at the Cosman Employment Agency. Jack makes advances to Cosman employee Polly, but he is thwarted by the arrival of her boyfriend, a towering police officer. Polly assigns Dinkle and Jack to babysit for Eloise Larkin's brother and infant sister, while Eloise and her fiance are out for the evening. The babysitting duties are complicated by the fact that Donald is something of a prodigy, as well as a self-proclaimed "problem child". The dull-witted Jack is soon outclassed by the child, and an attempt to lull the boy to sleep by reading the fairy tale Jack and the Beanstalk (Jack's "favorite novel") aloud fails when Jack stumbles over the larger words. Bemused by Jack's incompetence, Donald reads the story insteada role-reversal made complete when Jack falls asleep as Donald reads. In his slumber, Jack dreams that he is the young Jack of the fairy tale. In his dream Jack learns that the Giant, who lives in a castle in the sky, has stolen all of the land's wealth and food. The situation obliges the kingdom's princess to marry The Prince of a neighboring kingdom, whom she has never met. Jack must also make sacrifices, when his mother sends him to sell the last family possession, their beloved cow "Henry", to the local butcher, Mr. Dinklepuss. Along the way Jack meets The Prince, disguised as a troubador (who is kidnapped by the Giant soon afterward). The unscrupulous Dinklepuss pays Jack five "magic" beans for the cow. Upon returning home, Jack learns that the Giant has also kidnapped The Princess and Henry. answer the following question: What was the name of the person that Jack was outclassed by?
A:
Donald
