History Recap / TheSimpsonsS9E20TheTroubleWithTrillions

* TwoDecadesBehind: When they arrive in Cuba Burns is shocked to learn that Batista is no longer in power. Batista was ousted during the revolution of 1959.

** There is is no way Ned would be able to file his taxes that early. If Ned was doing his personal taxes, which is what it is implied he is doing, then he would have to wait until finishing up with his business taxes to figure out how much he personally owned to the IRS. However, that doesn't include any other deductions when doing an itemized deduction (as he puts cashier ribbon under personal expense) and most of the paper work from the IRS, mortgage companies, insurance, credit card companies, etc. wouldn't be in the mail until the first few weeks of the year, this was more true in the pre-internet days. The earliest Ned could do his taxes would be in the middle of January, if the only thing he had was his W-2 from his job and doing a standard deduction. If he had to do his business taxes, he would still have to wait for paperwork from the IRS, vendors, other business, the mall, and others before he could even think about filing.

** Mr. Burns's ancestor was at the original Boston Tea Party (which, in universe, was responsible for the extinction of a fish species by contaminating its habitat with tea).

-->'''APB''': Be on the look out for a maroon, 1939 Stutz Bearcat!

* DiscoDan: Mr. Burns' out-of-touch-with-the-times tendencies are in full display here. He thinks Homer is a reporter for ''Collier's'', which had ceased publication in 1957 (although it was briefly revived in 2012), and while in Cuba, was shocked to learn that [[UsefulNotes/FulgencioBatista Batista]] was no longer in charge. He also identifies a taxi as "the new Packard they've been talking about."

* OhCrap[=/=]ThisIsGonnaSuck: The [[https://frinkiac.com/img/S09E20/1139854.jpg look on Homer and Smithers' faces]] after they remind Mr. Burns that he's flying the plane... and he's about to attempt a landing.

* ArtisticLicenseEconomics: While a trillion dollar bill sounds like a cool idea, [[AwesomeButImpractical it would actually be impossible to spend because nobody, no matter how strong their economy, would ever be able to make change from it.]] Not to mention if you lost it, your country would go bankrupt.
