While unable to operate, he is able to give tips to the other surgeons due to his sense of smell and other clues, much to Frank's annoyance.
Frank, meanwhile, has been steadily winning money from the rest of the staff camp by betting on baseball games.
Hawkeye, aware of Frank's scheme, arranges it so that Frank's radio is connected to the camp PA, and then "broadcasts" a fake Indians-Yankees ballgame into it at night, with B.J., Klinger, and Radar providing background noise.
When the real game's final score (Yankees won, 8-1) is broadcast over the PA the next morning, Frank notices the different outcome, inadvertently blurts out that he listened to the game last night, and the other staff members immediately begin to accost him, demanding their lost money back.
However, shortly thereafter, Hawkeye appears in the nurses' tent with his eyes bandaged again, explaining that he had a relapse.
