Some days, I have nothing better to do than think about the Grimace.
From wikipedia:
"Grimace 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". Originally, Grimace was the "Evil Grimace", with two pairs of arms with which to steal milkshakes. After that first campaign, the character was revised to be one of the "good guys", and his number of arms was reduced by two. Commercials and merchandise generally portrayed him as a well-meaning simpleton, whose clumsy antics provided a comic foil to Ronald McDonald. The character was retained after the streamlining of the characters in the '80s."
