The Simpsons 138th Episode Spectacular/References

Trivia

 * The deleted "Robot Richard Simmons" scene was taken out of Burns' Heir because it didn't receive any laughs from the crew. However, when it was shown to fans, it received a huge amount of laughs.
 * The alternate ending for "Who Shot Mr. Burns" was made to fool the staff and animators so they wouldn't find out who really shot him.
 * This episode featured the short World War III, but the fourth act was cut out for time.
 * When Troy McClure is standing on the Simpson's staircase, a picture of the Simpsons as they appeared on The Tracey Ullman Show can be seen.
