In the teaser, Roy is looking for the sports section of the newspaper. When he finds it, Chet asks how many home runs Hank Aaron had hit the day before. This episode originally aired after the conclusion of the 1974 Major League Baseball season, when Hank Aaron's career home run total sat at 733; he would go on to play his final two seasons for the Milwaukee Brewers, where he would hit his final 22 home runs.
After Roy decides to switch his interest from horse racing to baseball, he tries to engage in small talk by saying "Bill Buckner's hitting over .300". He is referring to Bill Buckner, who played for the Los Angeles Dodgers from 1969 to 1976. He was part of the legendary Dodgers' teams of the 1970s, which also included Steve Garvey (1B), Davey Lopes (2B), and Ron Cey (3B). One note: Buckner is the player who let a ground ball go through his legs in the 1986 World Series, something that has dogged him until his death in 2019, as many people blame him as the reason the Boston Red Sox lost the World Series.
