Simpsons "Dancin' Homer" episode (#7F05). In the beginning of the show, the Simpsons attend an Isotopes baseball game. Blooper occurs during the singing of the National Anthem.
It regards the moon rising during the evening baseball game.
To illustrate how ridiculously long it's taking the Jazz Singer to belt out the pre-game national anthem, the moon is shown rising just above the bleachers where the Simpsons sit, and making substantial progress during the song.
The problem: this "rising" moon is not in accord with the moon phase shown (or vice versa). For those who know moon cycles, this is downright weird!
You'll see that the rising moon in the episode is clearly in the 1st quarter -- a crescent moon low above the horizon in the evening, which can ONLY happen within the first week after a new moon.
Yet a 1st quarter moon is always SETTING in the evening, not rising. It is still close to the sun
in the sky, and it's "chasing the sun" down to the horizon and then below at sunset.
The ONLY time you can possibly see a crescent moon RISING above the horizon is 1) in the early pre-dawn morning, during the third quarter of the moon's cycle, and the sunrise is soon to follow, or 2) during morning daylight, after the sun has risen, during 1st quarter.
So unless we're to believe that Springfielders go watch their baseball team play at about 5 AM, this is a definite blooper!
