Grimace

Grimace is a character featured in McDonaldland commercials. He is a large, purple anthropomorphic being of indeterminate species with short arms and legs. He is known for his slow-witted demeanor. His most common expression is the word "duh" before every sentence.

He had been voiced by Frank Welker and, sometimes, Larry Moran in the commercials, and Kevin Michael Richardson in the VHS series "The Wacky Adventures of Ronald McDonald". He was portrayed by Patti Saunders from 1971-1984 and Terry Castillo from 1984-2003.
