Hank cannot believe his luck when he is chosen to host the Japanese exchange student. He even manages to remember to get his permission slip signed - only for McKelty to steal it. With no signed permission slip, 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 Ms 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.
