30. Rigged voting machines.
Their 2008 gag about rigged voting machines which counted votes for the Republican party even when citizens chose Obama seemed spookily dead-on when several people complained about the exact same problem in the 2012 election.
29. 2016 Nobel Prize winner.
In the 2010 season opener Lisa, Millhouse, and a bunch of her nerdy friends have stayed up late to hear the winners of the Nobel prize, in which Krusty wins the Nobel Peace Prize.
So far, so Simpsons, but then we get a look at Martin’s betting pool card and we see Millhouse had predicted an Economics prize for Bengt R. Holmstrom, who actually went on to win in 2016..
28. Economic troubles in Greece.
Three years before the government debt meltdown in Greece that saw it become the first country to default on an IMF loan repayment, a throwaway gag on this 2012 episode predicted how outlandish the situation would become. A ticker on a rolling news station that Homer appears on reads “Europe puts Greece on eBay”.
27. Future phones.
In the episode (‘Lisa’s Wedding’) there was a scene where ‘future’ phones were used, and they had a shockingly similar function to today's Facetime.
26. The ebola outbreak.
Some people maintain that "The Simpsons" predicted the 2014 outbreak of Ebola 17 years before it happened. In a scene from the episode "Lisa's Sax," Marge suggests a sick Bart read a book titled "Curious George and the Ebola Virus." The virus wasn't particularly widespread in the 1990s, but years later it was the top of the news agenda.
