Ribbie and Roobarb were a pair of mascots used by the Chicago White Sox from 1981 to 1988 at Comiskey Park. After the Sox were sold in 1981 by Bill Veeck to an ownership group headed by Jerry Reinsdorf and Eddie Einhorn, the new owners, who were eager to draw on the 1970s popularity of such mascots as The San Diego Chicken, hired the design firm responsible for creating the Phillie Phanatic to create a new mascot for the Sox.
They debuted the pair of furry mascots in September 1981, but the fans never accepted the two, ridiculing them throughout their tenure with the team—both because of their ludicrous appearance, which had no apparent connection with the team, and also because they were seen as an attempt to eliminate Andy the Clown, who had performed unofficially at Sox games since 1960. "Rhubarb" is longtime baseball slang for a heated on-field argument; Ribbie comes from the acronym RBI, for runs batted in. Often reports will say ribbie instead of RBI to describe it. For most of the 1980s, the patrons at Comiskey Park ... were asked to endure the 'antics' of baseball's least appealing mascots, Ribbie and Roobarb. One looked like the dim-witted son of Oscar the Grouch, the other like a chartreuse anteater with a genetic flaw. After another failed mascot in the early 1990s was Waldo the White Sox Wolf. The White Sox introduced a new mascot, Southpaw, in 2003.
