After Ralph tells Alice he's too tired to go with her to her mother's, Alice tells him he can't stay home as she has nothing prepared for supper. Shortly after she tells Ralph there's fried chicken in the ice box.
Alice asks Ralph why he would go bowling with his annual bus company physical scheduled the next day and "risk passing it". She should have said "risk failing it" (or "risk not passing it").
The bowling team's name (Racoons) is misspelled on Ralph & Ed's bowling jackets.
Ralph incorrectly calls the heating pad a sleeping pad.
