Question: What other voice work was done by the person who voiced Ed Grimley's pet rat? Passage 1:Episodes of the show often featured Ed Grimley in several adventures, which start out as mundane, but turn very surreal and cartoonish, interspersed with science lessons from The Amazing Gustav Brothers, Roger and Emil, and a live-action segment with a "scary story" titled The Count Floyd Show presented as a show-within-a-show by Grimley's favorite television host, SCTV's Count Floyd (played by SCTV cast member Joe Flaherty). Grimley's fellow cartoon characters included Grimley's landlord Leo Freebus (voiced by Jonathan Winters), Leo's wife Deidre (voiced by Andrea Martin), his ditzy, amateur actress neighbor Ms. Malone (voiced by Catherine O'Hara; a female character by the name of Ms. Malone did appear on an SNL version of an Ed Grimley sketch on the season ten episode hosted by Alex Karras, but Ms. Malone was played by that episode's musical guest Tina Turner), and her little brother Wendell (voiced by Danny Cooksey). Ed owns a goldfish named Moby and a clever pet rat named Sheldon (voiced by Frank Welker). At the end of each episode, Ed would write in his diary about what happened in his day.
Passage 2:Historical negationism applies the techniques of research, quotation, and presentation for deception of the reader and denial of the historical record. In support of the "revised history" perspective, the negationist historian uses false documents as genuine sources, presents specious reasons to distrust genuine documents, exploits published opinions, by quoting out of historical context, manipulates statistics, and mistranslates texts in other languages. The revision techniques of historical negationism operate in the intellectual space of public debate for the advancement of a given interpretation of history and the cultural-perspective of the "revised history". As a document, the revised history is used to negate the validity of the factual, documentary record, and so reframe explanations and perceptions of the discussed historical event, in order to deceive the reader, the listener, and the viewer; therefore, historical negationism functions as a technique of propaganda. Rather than submit their works for peer review, negationist historians rewrite history and use logical fallacies to construct arguments that will obtain the desired results, a "revised history" that supports an agenda political, ideological, religious, etc. In the practice of historiography, the British historian Richard J. Evans describes the technical differences, between professional historians and negationist historians:
Passage 3:The Florida Reef (also known as the Great Florida Reef, Florida reefs, Florida Reef Tract and Florida Keys Reef Tract) is the only living coral barrier reef in the continental United States. It is the third largest coral barrier reef system in the world (after the Great Barrier Reef and Belize Barrier Reef). It lies a few miles seaward of the Florida Keys, is about 4 miles (6 to 7km) wide and extends (along the 20 meter depth contour) from Fowey Rocks just east of Soldier Key to just south of the Marquesas Keys. The barrier reef tract forms a great arc, concentric with the Florida Keys, with the northern end, in Biscayne National Park, oriented north-south and the western end, south of the Marquesas Keys, oriented east-west. The rest of the reef outside Biscayne National Park lies within John Pennekamp Coral Reef State Park and the Florida Keys National Marine Sanctuary. Isolated coral patch reefs occur northward from Biscayne National Park as far north as Stuart, in Martin County. Coral reefs are also found in Dry Tortugas National Park west of the Marquesas Keys. There are more than 6,000 individual reefs in the system. The reefs are 5,000 to 7,000 years old, having developed since sea levels rose following the Wisconsinan glaciation.
