552-episode FXX Simpsons marathon just started

Bleeding Gums Murphy will be there.

So will Disco Stu.

And just try to keep Troy McClure, Bumblebee Man, Hans Moleman, Dr. Nick Riviera and Cletus the Slack-Jawed Yokel from showing up.

At 10 a.m. today, FXX will celebrate its latest acquisition by launching the longest around-the-clock marathon in TV history: all 552 episodes of “The Simpsons,” plus “The Simpsons Movie,” in chronological order.

It will last 278 hours.

In October, SimpsonsWorld.com will offer on-demand access to every episode.

Until then, don’t try to be a hero. The Guinness World Record for consecutive TV watching is only 90 hours.
