Ken Griffey, Jr. did not understand his line "there's a party in my mouth and everyone's invited" and got quite frustrated when he was recording it. He was directed by Mike Reiss, and his father Ken Griffey, Sr. was also present, trying to coach his son. Roger Clemens, who made his own chicken noises, was directed by Jeff Martin, as was Wade Boggs. Mike Reiss directed most of the other players. Mike Scioscia accepted his guest spot in "half a second," while Ozzie Smith has said he would like to guest star again "so can get out [of the Springfield Mystery spot". Don Mattingly, who was forced to shave off his "sideburns" by Mr. Burns during the episode, would later have an actual "haircut controversy", while he was playing for the New York Yankees. The coaching staff forced him to cut his long hair, and was briefly dropped from the team line-up for not doing so. Many people believed the joke in the episode to be a reference to the incident, but "Homer at the Bat" was recorded a year before it happened. Many of the guest stars, including Terry Cashman, Wade Boggs and Darryl Strawberry all admit they are more well known because of their appearance in the episode, especially outside the United States, Cashman having "Talkin' Softball" requested more often than "Talkin' Baseball".
