Do you and your eyeballs have what it takes to watch every episode of The Simpsons in a row? FXX has essentially issued that challenge, announcing Wednesday that it will air all 552 installments of the animated Fox comedy over a 12-day period, from Aug. 21 through Labor Day. In case you’re wondering, yes, there is an actual world record for longest continuous television viewing, and it’s held by a pair of California residents, who consumed 86 hours and 37 minutes of Springfield high jinks during a Fox-sponsored event two years ago.
