Man that episode had a lot of great lines.

"[in a flashback when Mr. Burns was young]

Boy: You can't treat the working man this way. One day we'll form a union and get the fair and equittable treatment we deserve. Then we'll go too far, and get corrupt and shiftless and the Japanese will eat us alive!

Mr. Burns' Grandfather: The Japanese!? Those sandal-wearing goldfish tenders? Bosh! Flimshaw!

[Years Later]

Mr. Burns: If only we'd listened to that boy, instead of walling him up in the abandoned coke oven."
