Input: Question: What other series has the writer of "Lisa the Skeptic" worked on? Passage 1:In November 1988, a new development team within Microsoft (which included former Digital Equipment Corporation developers Dave Cutler and Mark Lucovsky) began work on a revamped version of IBM and Microsoft's OS/2 operating system known as "NT OS/2". NT OS/2 was intended to be a secure, multi-user operating system with POSIX compatibility and a modular, portable kernel with preemptive multitasking and support for multiple processor architectures. However, following the successful release of Windows 3.0, the NT development team decided to rework the project to use an extended 32-bit port of the Windows API known as Win32 instead of those of OS/2. Win32 maintained a similar structure to the Windows APIs (allowing existing Windows applications to easily be ported to the platform), but also supported the capabilities of the existing NT kernel. Following its approval by Microsoft's staff, development continued on what was now Windows NT, the first 32-bit version of Windows. However, IBM objected to the changes, and ultimately continued OS/2 development on its own.
Passage 2:In the world of sports, mascots are also used for merchandising. Team mascots are often related to their respective team nicknames. This is especially true when the team's nickname is something that is a living animal and/or can be made to have humanlike characteristics. For more abstract nicknames, the team may opt to have an unrelated character serve as the mascot. For example, the athletic teams of the University of Alabama are nicknamed the Crimson Tide, while their mascot is an elephant named Big Al. Team mascots may take the form of a logo, person, live animal, inanimate object, or a costumed character, and often appear at team matches and other related events, sports mascots are often used as marketing tools for their teams to children. Since the mid-20th century, costumed characters have provided teams with an opportunity to choose a fantasy creature as their mascot, as is the case with the Philadelphia Phillies' mascot, the Phillie Phanatic, and the Philadelphia Flyers' mascot, Gritty.
Passage 3:"Lisa the Skeptic" is the eighth episode of The Simpsons' ninth season. It first aired on the Fox network in the United States on November 23, 1997. On an archaeological dig with her class, Lisa discovers a skeleton that resembles an angel. All of the townspeople believe that the skeleton actually came from an angel, but skeptical Lisa attempts to persuade them that there must be a rational scientific explanation. The episode's writer, David X. Cohen, developed the idea after visiting the American Museum of Natural History, and decided to loosely parallel themes from the Scopes Monkey Trial. The episode also makes allusions to actual hoaxes, such as the Cardiff Giant.
