A Bill Full of Dollars - S13-E6
Continuity mistake: Peggy, Minh and Dale feel responsible for Dale losing all his money after investing in the stock market. To help him out, they pool all their money and the loose bills fill a large basket. After the money ($5000) is stacked and bundled, there are only five small bundles. They put the bundles in the basket and take it to Bill's House. When the money is placed on the living-room table, there are only three bundles.
Answer: If you are talking about the "Thou shalt not do this, thou shalt not do that" song, I'm not sure if a song like that actually exists. Green Day, the guest voices on the episode, might have just been improvising to keep their appearance from being too obvious.
