Hank is chosen to host a Japanese exchange student. He even manages to remember to get his permission slip signed, but there's trouble when school bully McKelty steals it. With no slip to present to Miss Adolf, Hank is in danger of not being allowed to take part. To show how committed Hank is to the exchange programme, Rosa organises a Japanese banquet for Miss Adolf and Mr Rock. The banquet ends in disaster: an escaped lizard, marauding crickets and a fainting Stan, who covers Ms Adolf with sushi. All looks lost, until Rosa uncovers Ms Adolf's secret passion: karaoke.
