Ronald McDonald, the McDonald’s “chief happiness officer” may be forced into retirement if the “Corporate Accountability International” coalition have it their way.

They say Ronald McDonald  is fueling childhood obesity, and the Boston-based nonprofit is planning a retirement party today at a McDonald’s in downtown Chicago, according to the Chicago Tribune.

The group, made up of health care professionals and parents, has taken on Joe Camel in the past. Whether it can end Ronald’s 50-year run as corporate spokesman remains to be seen. McDonald’s Corp. calls him its “chief happiness officer” and points to the character’s role in promoting Ronald McDonald House Charities, among other philanthropic causes.
