Quake - Good enough for William Conrad
Wiki had a neat summary for Quisp and Quake. I understand Daws Butler being Quisp but William Conrad was the voice for Quake?
Quisp and Quake were two sugar-sweetened breakfast cereals originally released in 1965 in the U.S. by The Quaker Oats Company and generally advertised together (during the same commercial) as products competing against each other. The very successful ads were cartoons created by Jay Ward of Rocky and Bullwinkle fame, and used some of the same voices, including Daws Butler as the voice of Quisp (an alien) and William Conrad as the voice of Quake (a miner).
In 1970, a contest was held by Quaker Oats to see whose cereal was the more popular of the two. In 1972, Quisp won, and Quake retreated underground. Quake, the cartoon character, reappeared in a new cereal called Quangaroos where he obtained an orange kangaroo as well as putting his mining helmet down in favor of an Aussie motif.
In the late-1970s, Quisp was removed from grocery stores due to low sales. It re-emerged in the mid-1980s, and finally was re-introduced in the 1990s as the "first Internet cereal" and is still in limited distribution.
Starting in early March 2008, many Dollar General Stores (especially in, but not limited to, OH, PA, WV, and much of the Northeast US) will begin selling Quisp (as well as other classics such as King Vitaman, Crunchy Corn Bran, and Honey Graham Oh's).
