The Simpsons S13 E15 Blame It on Lisa

"Just a product of society that's lost its good manners."

When Homer gets the family's telephone service cut off for refusing to pay for calls made to Rio de Janeiro, Brazil, Lisa confesses that she was the one who called Rio after sponsoring an orphan who goes missing. She convinces the family to travel to Brazil to look for him. However, once there, they have no luck finding him, and Homer is kidnapped.
