Bullfrog

Bullfrog (no last name given) is a fictional baseball player mentioned in the 1983 film, A Christmas Story, by Old Man Parker (played by Darren McGavin) when he tells his wife that the Sox (probably the Chicago White Sox since the movie is set in the fictional town of Hohman, Indiana) traded "Bullfrog" for "Four Eyes" Shottenhoffer, a utility infielder. The entirety of the dialogue about the two players is as follows:

Old Man Parker: "They traded Bullfrog. I don't believe it."

Mrs. Parker: "What's that?"

Old Man Parker: "Well, for Christ's sake, the Sox traded Bullfrog... the only player they've got, for Shottenhoffer. "Four Eyes" Shottenhoffer, a utility infielder. Got a whole goddamned team of utility infielders."

Mrs. Parker: "That's nice."

It seems very likely that this character is either supposed to be or is based on Bill Dietrich, who was nicknamed Bullfrog and would have been with the White Sox around the time the movie is set.
