Background: Ballmer was born in Detroit; he was the son of Beatrice Dworkin and Frederic Henry Ballmer (Fritz Hans Ballmer), a manager at the Ford Motor Company. His father was a Swiss immigrant, and his mother was Belarusian Jewish. Through his mother, Ballmer is a second cousin of actress and comedian Gilda Radner. Ballmer grew up in the affluent community of Farmington Hills, Michigan.
Context: In 2005, Microsoft sued Google for hiring one of its previous vice presidents, Kai-Fu Lee, claiming it was in violation of his one-year non-compete clause in his contract. Mark Lucovsky, who left for Google in 2004, alleged in a sworn statement to a Washington state court that Ballmer became enraged upon hearing that Lucovsky was about to leave Microsoft for Google, picked up his chair, and threw it across his office, and that, referring to former Google CEO Eric Schmidt (who previously worked for competitors Sun and Novell), Ballmer vowed to "kill Google." Lucovsky reports:  At some point in the conversation Mr. Ballmer said: "Just tell me it's not Google." I told him it was Google. At that point, Mr. Ballmer picked up a chair and threw it across the room hitting a table in his office. Mr. Ballmer then said: "Fucking Eric Schmidt is a fucking pussy. I'm going to fucking bury that guy, I have done it before, and I will do it again. I'm going to fucking kill Google."  Ballmer then resumed attempting to persuade Lucovsky to stay at Microsoft. Ballmer has described Lucovsky's account of the incident as a "gross exaggeration of what actually took place".  During the 2011 Web 2.0 Summit in San Francisco, he said: "You don't need to be a computer scientist to use a Windows Phone and you do to use an Android phone ... It is hard for me to be excited about the Android phones."  In 2013, Ballmer said that Google was a "monopoly" that should be pressured from market competition authorities.

Problem: Background: Pierrot (French pronunciation:  [pjeRo]) is a stock character of pantomime and commedia dell'arte whose origins are in the late seventeenth-century Italian troupe of players performing in Paris and known as the Comedie-Italienne; the name is a diminutive of Pierre (Peter), via the suffix -ot. His character in contemporary popular culture--in poetry, fiction, and the visual arts, as well as works for the stage, screen, and concert hall--is that of the sad clown, pining for love of Columbine, who usually breaks his heart and leaves him for Harlequin. Performing unmasked, with a whitened face, he wears a loose white blouse with large buttons and wide white pantaloons. Sometimes he appears with a frilled collaret and a hat, usually with a close-fitting crown and wide round brim, more rarely with a conical shape like a dunce's cap.
Context: He is sometimes said to be a French variant of the sixteenth-century Italian Pedrolino, but the two types have little but their names ("Little Pete") and social stations in common. Both are comic servants, but Pedrolino, as a so-called first zanni, often acts with cunning and daring, an engine of the plot in the scenarios where he appears. Pierrot, on the other hand, as a "second" zanni, is a static character in his earliest incarnations, "standing on the periphery of the action", dispensing advice that seems to him sage, and courting--unsuccessfully--his master's young daughter, Columbine, with bashfulness and indecision.  His origins among the Italian players in France are most unambiguously traced to Moliere's character, the lovelorn peasant Pierrot, in Don Juan, or The Stone Guest (1665). In 1673, probably inspired by Moliere's success, the Comedie-Italienne made its own contribution to the Don Juan legend with an Addendum to "The Stone Guest", which included Moliere's Pierrot. Thereafter the character--sometimes a peasant, but more often now an Italianate "second" zanni--appeared fairly regularly in the Italians' offerings, his role always taken by one Giuseppe Giaratone (or Geratoni, fl. 1639-1697), until the troupe was banished by royal decree in 1697.  Among the French dramatists who wrote for the Italians and who gave Pierrot life on their stage were Jean Palaprat, Claude-Ignace Brugiere de Barante, Antoine Houdar de la Motte, and the most sensitive of his early interpreters, Jean-Francois Regnard. He acquires there a very distinctive personality. He seems an anomaly among the busy social creatures that surround him; he is isolated, out of touch. Columbine laughs at his advances; his masters who are in pursuit of pretty young wives brush off his warnings to act their age. His is a solitary voice, and his estrangement, however comic, bears the pathos of the portraits--Watteau's chief among them--that we will encounter in the centuries to come.
