While recalling the times she was embarrassed on family vacations, Marge remembered the family's trip to Amish Country. Homer stuck ice cream cones on everyone and everything he encountered, taking great delight in the fact that no one was getting angry, fighting back or reacting at all: "Hee hee! I can be a jerk and no one can stop me!" Homer's good time came to an end, however, when he stuck an ice cream cone on a mule and it kicked him.
Marge was embarrassed by Homer's boorish behavior in Amish Country, but said that the family's trip to Sandy Beach was even worse.
